New Thoughts in Public Transportation
Matthew Shaylor writes "The BBC has the following article about an ultramodern public transport system to be tested in Cardif. Unlike conventional public transport, this consists of small cars that running on tracks can automatically take themselves to the correct destination. This allows there to be a mesh of tracks and stations thoughout a city, as opposed to traditional transport which tends to run along corridor routes to a city center. An interesting paper is available. Future versions may have dual control to allow people to drive the cars from the nearest station off the track to their homes. A true replacement for the car!"
That would be the one in Wale, right?
this isn't a new "concept", but I find it interesting that something that always seemed (to me) to be one of those sci-fi concepts that was, while not impossible, very very improbable due the the immense infrastructure required - to see this now actually being discussed as a possibility. it's actually quite interesting.
You see, without that little doohicky, the universe stops.

If I ride a Sewgay, can I fit it onto one of these cars to that I don't run the battery down if I'm going across town?
One of the problems with things like this is how does it work when you go to do the weekly shopping. Imagine you have a very hungry family of 2 adults and 3 children. With this system you'd have to make sure your little tram took you from right outside the supermarket to your front door or else you'd be changing many times with lots of heavy bags of shopping.
I'm out of my tree just now but please feel free to leave a banana.
I'm v.pleased to see from the photo that they will allow bikes to be taken aboard.
The combination of bike and public transport is perfect for me and many others.

Larger cities have no way of building such infrastructure and already have subways which can carry far more people than this system. It is a good replacement for light rails suitable for the sprawling suburbs, but since taking one means you won't have access to your car it probably will never take off.
The best solution is really robotic cars. We should enact legislation so that all new roads built have some sort of simple radio emitters in them to help guide the robotic cars. Then we can all read slashdot on our wireless neighboor LANs while we ride to work every day.

So... you swipe a card, punch in a destination, and suddenly they have a very neat record of where you've gone using public transportation. Nice.
Aside from that, it's an interesting idea; you don't necessarily have the hassle of figuring out bus schedules. And you don't have to deal with a cab driver who barely speaks English and is quite willing to drive you around New York for two hours because you don't know that your destination is really only a fifteen-minute drive from the airport. So in that sense, it's nice.
I especially appreciated the photo that shows a bike will easily fit into these vehicles... good call! Heck, that means fitting a Segway in there would be pretty easy...
People are never as simple as their stereotypes. This applies equally to Christians, Muslims, and Emacs-lovers.
Nothing beats the freedom of hopping into my car, when I want to and not waiting for public transportation, on their schedule. And taking the long way home, instead of the fastest route when I want to.
If that dual version becomes available, I'd like to see it, since it allows for some of the freedoms. But how would I return it?
I'm not afraid of falling, it's the sudden stop at the end that frightens me.
This sounds a bit like a technology that would preceed the public transportation seen on Futurama.
The real question is, do these cars read your destination from your mind or can you just speak directives to them like turbolifts?
The List of Grievances with Slashdot.
.. is that the people constructing these tracks don't have a large enough supply of "curved" sections of track, and always have plenty of "straight" sections of track. Thus, they keep having to go back to Toys R Us to buy more "curvy" tracks...
If they plan to deploy these things on existing streets -- which, IMHO, seems like the logical thing to do -- how do they plan on preventing collisions and other problems related to a standard car? I'm sure that if these things are computer controlled, you could have a model of traffic efficiency, but when you mix it with erratic human behaviour, how will it cope?
My other sig is funny!
If all the cars are the about the same size and shape, how would people with money show off how rich they are? Also, if these automatically take people to where they want, there would be no need for chauffeurs, once again robbing wealthy people of thier importances.
on a side note, doesn't the picture of the ULTra on the elevated track remind you of the Monorail epsiode of the simpsons?
"Facts are meaningless. You could use facts to prove anything that's even remotely true." - Homer Simpson
Traffic congestion is still a problem at intersections, as parking them. I'd also like to see how it handles routing through the city.
::snicker::
Also, now we're talking about tracks. What happens when one jumps the tracks? It just sit there hold up everything else behind it?
How are we going to accomodate for all these tracks in existing cities? It's grossly expensive and takes up space. Might as well have the Big Dig in every major city.
And us Bostonians know how the Big Dig is coming along

As long as I can fit my exoskeleton in, that's fine.
Just got to wonder though, we already have this neat invention which you can use to take you places (supermarket, home etc.) It's more commonly called a taxi.
I suppose a combo taxi/hire car might work... It's got to catch on first (and recoup that 45 million they're investing).
This is really the self driving cars question, taken from the oppisite approach.
I still think that the best way to tackle this would be a solution that relies as little as possible on things built into the ground. It's 2002, and we have fast computers and fairly accurate GPS guidance. I don't see any reason why the earth part of the system should be more than stipes of whatever color reflective paint on the ground. It's easy and cheap, and it won't ever need upgrading. Then car computer guides itself with the paint lines, but uses GPS to ditermine it's location and to make decisions about turning and stuff. Maybe some kind of WAP based thing where cars close to each other share location and velocity information. Of course, this all comes in a box under the hood with a couple cables sticking out. The WAP could accept software upgrades, and if new hardware is neccessary than you just have to take all the cars to the shop rather than dig in half your roads.
beats circut switched traffic any day. now i see why this is on /.
"i was saying gnu-rd"
Back in my freshman year in college, I proposed and worked on a very similar transportation system, called HSTS (High Speed Transit System). Other engineering students collaborated with it as well. We even had a student code a Java applet that simulated the whole thing. The biggest problem we found was what would happen if the cars were going really fast, and the power suddenly went off... We used the term "Mass Death". :^)
Slashdot's first reaction to VMware
Didn't we used to call "tracks" small cars would take directly to their intended destination something else? I could swear they were called "roads"...
One of the advantages of public transportation is that it's a CLEANER form of transportation - 25 people on a bus produces less pollution than 20 cars on the road. Put everyone back in their own car and you lose this advantage.

Finally someone is thinking about my favorite transportation system: people bubbles. I've thought for a while that this is the way to go. point to point, private, automated. A huge infastructure is required, but you could also have aggregate links for city to city, aka a train or something that your bubble would drive onto and would take you to the next city.
Why are the brits, or most OTHER non American so hung up on friggn trains ? This isnt a flame(usually a sure note it probably is) But WHAT about train or derivation of it makes it SO appealing to people ? Japan , Ok I can actually see a use there, its like a goddam ant farm. In the US we have the space. Contract roads and transportation to a PRIVATE company, tell em they get paid (for improvements etc) on a per car on time basis. You'd see a hell of an increase in the efficeny of traffic.
At the point they start talking about "driving" the things home , why not just use a car ?
This concept reminds me of those Antique Cars on a rail at Disney World. you can drive a little, but have nor real control.
The infrastructure needed for this would be overwhelming.
Why when everyone talks about "Future" or "Ultra-Modern" does it reming me of a 1950's popular science article like the one on JET POWERED SUPERSONIC ZEPPLINS ??? Yeah they hit that one right on the nose.....
How about this ??? We widen roads, use quality materials, stop contracting to the lowest bidder so they fall apart in 5 years, and quiet and clean up emissions some more, NAW thats too sensible....
PS, I love picture #5 on the Paper , reminds me of the tube in "Logans Run" that musta taken creativity....
Sig went tro...aahemmm.....fishing........
Instead of installing some corrider-constrained, incredibly expensive Mag-Lev system of dubious value which does nothing to address the nightmare of getting from neighborhood to neighborhood in this tangle of hills, gullies and twisty streets they call a City, they could use existing arterials (supplimented perhaps with a couple of new ones) to *greatly* expand the reach of public transportion and make it practical to ditch the now-mandatory two-car-per-family lifestyle.
Phew, feels good to get that off my chest...
I hate to say it, but I for one, would not want this. I live in Atlanta, a very large city with huge traffic problems. Well, my thoughts are this: I deal with the traffic here everyday (worst in America 5 years running btw) and there is a simple reason I do it. MARTA (Metro Atlanta Rail Transit Authority--I think) is not safe. Sure, these cars seem nice, but I don't think it will ever catch on here in the US. I wish it would, we throw enough smog and pollution in the air as it, but for my money, and safety, I will stick to my car. I have never been to Cardif, so I cannot speak for there, but I will speak of what I know.

I am not trolling, but you will probably mod me as such since my opinion doesn't jive with the new tech is good slant of the article.

A true replacement for the car
From the BBC
In the final scheme, passengers would use the vandal-proof vehicles as personalised taxis, using a smart card to tap in their destination and pay the fare.
This does not ease congestion on the roads; mass transit systems help with that - cramming 50 people onto a bus that is significantly smaller than 50 cars.
I assume that the track for this Cardiff scheme will interfere with the road system - ULTra users want to get to the same sort of places as car users after all - so having lots of these running around each containing a single person is just as bad from a congestion standpoint as having these people in cars.
Of course, another assumption is that people will use the mass transit system - sitting in a traffic jam behind an empty bus is v.annoying.

RUF combines the best of cars with the best of trains
The RUF system is a system where all vehicles can drive in 2 ways (Dual-Mode). They can either use the normal roads or they can "ride" on top of a triangular monorail.
The RUF vehicles can both be cars (ruf) and busses (maxi-ruf). The rail (guideway) is a very slender triangular monorail made from 20 m long modules and carried by masts.
When the vehicles "rides" on top of the monorail, the center of gravity is placed below the top of the rail, so the stability is very high. Derailment is impossible. It is possible to squeeze the top of the rail in order to make an emergency braking. This way it is possible under all circumstances to brake in a very short time. Short safety distances means large capacity.
Energy consumption is very low due to the close coupling of vehicles to form a train. This principle also increases safety, since collisions within the train are eliminated when the vehicles already touch each other.
The rufs are electric vehicles with small batteries. The batteries are partly recharged while the ruf uses the rail.
This allows there to be a mesh of tracks and stations thoughout a city, as opposed to traditional transport which tends to run along corridor routes to a city center
I've always though the city could use a few more tracks. Seriously though, why do these things have to go to every nook and crany of a city, why cant they just drop you off and let you walk a couple blocks to your destination?
OK, I know we're becoming lazier every day so I have four words for you: George Jetson People Mover. You'll never have to take another step again.
I Heart Sorting Networks
Working from memory, one problem they hit was the decision of whether to go for the ultimate taxi-like model, as here, or with some intermediate-sized light rail cars. The problems I recall with the taxi-like model included the problem that they couldn't get them connected to enough points for people to actually use them enough to pay for the service; and nightmare scenarios about someone's grandmother being trapped in an unmanned small car with a deranged killer.
I'm hoping someone else can come up with the title of the book on the French experiment I'm thinking about. It focussed much more on the social problems with making this kind of project happen than on any particular technical difficulties.

Here's an article (in French) about such idea as it was discussed about in France in May 2001. ...
A Google translation ca be found here
Trolling using another account since 2005.
There was an article in Scientific American about three years ago regarding the advances in public transportation made in Curitibo, Brazil. Their basic idea was to redesign all their roads from the standpoiont of getting people around. They placed seperate bus lanes on each road (seperate physically from the other lanes), and people paid to enter the bus stop instead of the bus. This meant people quickly entered the bus at each stop, without anyone digging around for change when entering the bus, etc. And the seperate lanes meant the buses went from place to place without much hinderance from car traffic. Also, their roads were all laid out with a great deal of thought, resembling a darts target with circular and radiating routes. The system worked remarkably well, and most people used public transit to get around.
Its amazing what can be accomplished when someone actually puts real thought into the system they're developing.
Some men spend their entire lives trying to kill themselves for having been born. --Ross MacDonald
The combined system (i.e. cars, which hook on to the public transport for longer journeys) seems to be the optimal solution for combining public and private transport.
In cities, this could lead to a much higher passenger throughput than roads, and for long distance journey, driving onto some kind of high-speed conveyor belt would have most of the advantages a train has, while retaining the mobility of a car once you exit it.
However, an efficient system for entering/exiting such a system is the difficult part: Of course, you could just stop everything to let one vehicle get on/off, but that's hardly optimal.
Another good web site on the topic is Taxi2000.
Make sure you check out their FAQ.
The important topic that's always brought up is infrastructure. The beauty of the PRT design is that the infrastructure costs aren't all that appalling, since all the system needs to run is a narrow elevated track which can be built above existing roadways (so no right of way issues, etc). Yeah, it's more expensive than bus stations, but it's *way* cheaper than tunnels or elevated train track.
In the final scheme, passengers would use the vandal-proof vehicles as personalised taxis, using a smart card to tap in their destination and pay the fare.
A few weeks later:
A top security manager is quoted as saying that "vandal-proof" doesn't really mean vandal-proof, or something
There is no
Places like North America that already have a huge transportation infrastructure would find it expensive to implement one of these, good to see that some European countries are testing them out now.
I dont know about some of you, but I hate driving. I'd much rather have an automated transport that could take me where I need to go without having to deal with Metro transit and all the crazies on the bus.
I'd rather have this ULTRA ;-)

In the old SIMCITY days, I always had problems with roads. Until one day, when I decided to make an entire city with railroads only. Worked wonderfully. :)
Looks like it'll happen in real life now.
Apparently this is not the only project working on light passenger load rail systems, check out the Light Rail Transit Association's website for a whole host of details about other projects around the world (mostly in Europe though, figures...) and a bunch of other stuff. Note: this includes trams and other slightly less advanced projects than the one mentioned in the BBC article, but its still worth checking out if there is more you want to learn about the field.

One problem, there's no conductor. I mean like a guy who is gonna sit there and say "no, don't destroy the inners of the vehicle.
What happens if before I get to my stop, I disable my car somehow and cause congestion? What about the congestion of people just getting in and out of a car serially vs in parallel like a subway does?
Sounds cool, but somehow doesn't. Unless the stations are as big as parking lots and these cars can pass one another, I'm not too into this idea.

Blar.
Public transportation networks are not pieces of software. It's not the futuristic design and technical niceties that count, the issues are a omplex entanglment of environmental, economical, political and social factors.
Bottom line : don't worry, it's gonna be the same commute for you in Cardif and all over the world for a long time
Would this make the new segway obsolete? =)
I SURVIVED THE GREAT SLASHDOT BLACKOUT OF 2002!
I think this is a great concept. We have the technology right now to create a system of public transportation that can be autonomous, however I think that the public doesn't want to give up control of how they get from point A to point Z. A system where cars go from one point to another (whether on tracks or by GPS and sensors), coupled with some of the Segway devices to go "the last mile" if neccessary and there could be an efficient, clean system of transportation. I think this is a step in the right direction.
except instead of using one of these cars, you drive your own car onto a pallet that will take you and your own car to the destination of your choice... and this one idea will not work because people dont want to give up their own cars (or add another one to the drive)

What kind of volume will it handle? From the looks of the things you'll need almost as many of those little driverless cabs as you do cars in a given urban area. That's going to cost! So what do we do to pay for the system, give up our cars and contribute the money that we spend on them to this system? Then what are we supposed to do if we want/need to travel outside the area serviced by this or other public transit systems? Ride our bikes? What if it's 300 miles away? Pouring rain? I don't think so Vern! I'm sorry but while it's a good attempt at replacing the automobile, it has a ways to go before it replaces the automobile's freedomof movement that our society's become accustomed to to the point of being dependant on it.
You're using her as bait, Master!
Americans tend to take a very negative view of public transportation. Part of this is due to the fact that it's public, and the public includes people who are drunk, abusive, and smell bad. People you would never ride with by choice. Even though they make up a small minority of the bus- and subway-riding public, they're enough to spoil the experience and make one not want to ride public transportation.
These transport pods look like they'd eliminate most of that problem, as they're small enough one could travel alone or with a small group of one's own choosing.
The dedicated track part could still be a problem. Americans like to go where they want, when they want (doesn't everyone) and with the ready availability of (polluting, road-clogging) cars, I don't see them opting for any track-based transport system in the near future. Americans also take a kind of pride in their vehicles (witness the huge number of heavy, expensive, rollover-prone "off-road" vehicles that have never been off a road). Maybe this kind of thing will work in Cardiff, but to really make an impact on the environment, petroleum industry etc., one needs a system that will work in the U.S. Where the cars are.

Your reality is lies and balderdash and I'm delighted to say that I have no grasp of it whatsoever. - Baron Munchausen
This is a concept commonly refered to as Personal Rapid Transit (PRT), a subset of Automated People Movers (APM) found at many airports. PRT has been around for a while and has somewhat fringe supporters (like me). Edward Anderson at the University of Minnesota has generated some of the most credible system designs and incorporated under Taxi2000. In fact, Raytheon developed a full test track of Anderson's concept outside of Boston; Bostonians can visit thier Marlborough, MA facility and see the future,!
The reason that PRT remains a fringe concept is related to economic challenges, not engineering ones. Although there are claims to the contrary, the general problem is that - like all public transit - PRT require a very high inital capital outlay. In dense urban areas, right-of-way costs are prohibitive. However, just as with information networks, public transit networks generate positive externalities: the larger the system, the more useful it is to everyone.
Furthermore there is little incentive to invest in expensive public works projects have prevented the testing of a fairly unproven technology. Public agencies would much rather invest in light rail systems that they have seen before than fancy driverless systems. Also, there is no conclusive proof that these decentralized systems can sustain the high corrider passenger/hour throughputs that make public transit so desirable for really dense urban areas.
Hopefully, projects like Cardiff will succeed and PRT will get recognition and legitimacy, but this is a technology that has been kicking around for a while and - as you can probably tell - is not insanely complex. As usual, economics and public policy get in the way of interesting engineering!
If Kamen's Segway becomes as popular as I think it will, Segway busses will be deployed in every major city to take advantage of this new class of mass transit passenger.
Segway riders will enter and exit this special "tall" bus or subway car on their own vehicle via a special ramp at each stop. There could also be a charger for each passenger/sub-vehicle and a small workspace (with ethernet, of course) on the inside of this vehicle as well.
Something this light would be very nice for other reasons; large buildings could have a mezannine-level entrance for rail vehicles, keeping ground level less cluttered and making it easier to get people in and out.

I've heard about something like this before, it is a mass-transit train system that runs on "streets" rather than tracks. Interesting, to say the least.

I find it interesting that we keep proposing (and implementing) systems that are really quite "space age" whatever that means, but the actual face of the world doesn't seem to change that much. This is such a fascinating idea, and one that I think has quite a bit of merrit. The only problem that I see is that of mixing this and regular traffic. I don't want to be trapped inside one of these little boxes toodling allong at a leisurly 25mph and have some jackass with his suv and cellphone run over me doing 50. I know the solution described in the article runs on a special track, but for a mass transit solution to work and gain wide use in anything but the largest cities, it has to share the infrastructure with regualr vehicles, otherwise it is often prohibitively expensive.
I know that mass transit works, but it works best in very dense population centers, because it is limited to specific routes. What if only one of your destination endpoints is near a mass transit station. Then you either have to walk or drive to the terminal. That works durring summer, or if you live in a warm dry climate, but right now I have to think twice about walking across the parkinglot to get my car it is so cold outside. I guess my point is that mass transportation needs to be nearly door to door or it will not gain wide acceptance.
When I want your opinion I will beat it out of you.

Err Cardiff has been there quite a bit longer than either NewYork or LA. Of course it can be done if the city wants it to be done.
The Underground in London probably got a similar response when they first built it. Then they built one in Paris and the rest is history.
Cardiff isn't a new town, which is why it has problems, it was started a long long time before cars and hence it needs new solutions as its not been built for cars ala NewYork and LA.

Urban Light Transport has more information on their web site, including some much higher-res images, FAQs and other info.
The most interesting (and not really mentioned) factor is that the automatic taxis don't travel on predetermined routes, they navigate their small network of paths to get to your destination.
The real problem is going to be pissed people on the way back from the pub throwing up in it.
If yer in a taxi they can hit you lots until you clear it up any pay for cleaning.

"In the final scheme, passengers would use the vandal-proof vehicles as personalised taxis, using a smart card to tap in their destination and pay the fare."
How exactly are these vehicles vandal proof?
What stops me from spray painting "Frodo Lives"

I hope this idea makes it. One of my (and many other persons') complaints about public transport is that it isn't direct enough; there's no way to get from point A to point B without first going through point C, waiting twenty minutes for a connection, then through points D and E before finally arriving at B. The only thing that will get people to use public transport is if it's faster than going by car.
I also someday dream of a system (alas, a long way off) by which none of us actually drives cars anymore -- computer-controlled cars will whisk you along at arbitrarily high speeds to take you to your destination, with little to no risk of automobile accidents. If the system were computer-controlled and more-or-less guaranteed safe, speed limits would no longer be an issue, traffic lights would be limited or non-existent (and you wouldn't have to worry about them anyway), and you can talk on your cell phone all you want. But, alas, this would require a great deal of infrastructure improvement and better sensor technology.
But possibly this new Welsh experiment will be the first step...
So what's the benefit of this kind of system? Individualized transport to anywhere. We already have a system like that... cars! The only thing we do with this system (at a cost of zillions of dollars) is remove the task of driving from people. The benefit of public transportation is the gain from economies of scale. Get lots of people into one machine (a bus for example) and you need less resources to move these folks around and reduce the number of vehicles on the street. The type of system mentioned here does not truely benefit from any economies of scale.
Could someone explain to me how this is different from having electric cars? with electric cars we wouldn't need the rail system and we can drive them home.
The only interesting thing about this is the fact that if they stayed on the tracks, you wouldn't need as much parking, and people wouldn't have to have massive SUV's to compete with the neighbours. as soon as they can leave the tracks people will want to own their own and they will want one that is bigger (and uses more electricity) than everyone else's. What are we gaining then?

I think you find that means Libya and Iraq, not Wales.
A true replacement for the car!
This is not a replacement for the car, not even close. It sounds to me like nothing more than an overglorified bus.
But put your daily commute asside. What if you want to leave the city? I doubt these things will take you on a trip somewhere else!
If people could report dirt, etc. in the vehicles or have security cameras take snapshots before and after each use of the vehicle (to avoid privacy issues with monitoring people), you could tell who left what and charge them for being slobs. You could use the extra fees to keep the system neat, or ban chronic offenders from using the network.

West Virginia University has something that sounds awfully similar to this in their Personal Rapit Transit (PRT) system (http://www.arc.wvu.edu/transportation/PRT.html).

Of all the ULT concepts I've seen, I like SkyTran the best. Putting a raised track on light poles is a great idea, as is the switched on-ramp. I can really see these getting up to 100mph (160kph)
As a dedicated transit rider, I love the idea of hopping into a vehicle, setting a destination, and hopping out when I'm there. Let's hope these take off.
Until then, I'll settle for a Segway. :)

This system could not replace cars for this reason alone (not that it was necessarily meant to).

If you want to make an apple pie from scratch, you must first create the universe. -- Carl Sagan
I had this idea several years back- although mine was larger in scale -totally replacing cars and being run by a central computer :p
Presently, most cities are in no way, shape or form set up for this sort of thing. Not just in term of tracks, but also in the dispersal of housing and business. Not to mention, especially in America, the car culture has mass transportation over a barrel.
Aggrivating this... we've seen smaller things like this in the past in various American cities, for instance Jacksonville Florida's 'People Mover' and they've gone over like a lead balloon.
Your mileage may vary, folks.. if anything's been shown in the past people *hate* to change their patterns of behavior.
With the demise of netvan and the undesirability of purchasing a car solely to go to the grocery store I, for one, would find a mass transit system that would drop me off at my front curb very useful. Add to that the fact that getting a cab at my local food store is next to impossible (while finding one 6 blocks away is easy, go figure), and the physical challenges (read:impossibility) of carrying 15 bags of groceries on foot, and even the most casual, non-knee-jerk-cynical observer can see the usefulness of such a system.
... making traffic a little worse in the short run might be just the kind of incentive that would help speed adoption of such a system.
As for it being "out of the question" that such could track systems could be laid down in a major city, don't be absurd (not you, but another poster in this thread). Major cities are exactly where this kind of thing would be most useful. Like Europe, they could be integrated into the existing streetplans a la streetcars. If the traffic implications are too significant (possible during the installation and early use, likely the opposite once such a system were adopted widely) they could be built on an elevated track. Personally, I'd just take lanes away from old-style cars
Of course, entrenched interests such as automobile manufacturers and taxi drivers are likely to raise a stink and do everything they can to slow adoption of such a system, but that sort of thing should be resisted and fought, not pandered to. Alas, in an age where the government spends more time and money trying to preserve the business models of buggie whip manufacturers (c.f RIAA, MPAA, DMCA, SSSCA, Copyright extentions, etc.) rather than promoting the adoption of new technologies and the new capabilities they promise (c.f. universally accessible, virtually cost-free libraries, free sharing of information, etc.) the future we face, at least in the short term, is not an optomistic one at all.

I really really wanted to be able to take public transportation to work. It's a 23-minute drive to work, I was willing to double that time to take public transportation. If I board the bus at 7:03am, I don't get to work until 8:40! I end up having to go clear into downtown Denver and then back up north for a drive that's not even 15 miles. I just moved closer to work so that I could avoid a 1hr+ commute (which, by the way, was over 2 hours by bus), so why would I want to ride a bus for over an hour and a half? And Denver is supposed to have really good public transportation! Bottom line (in Denver and the two other major cities I've lived and worked in) is that if you don't work or live downtown, public transportation is pretty much useless.

robotic cars would go a long way to reducing congestion synonymous with rush hour. congestion is basically brought on by a) consistently bad high-latency decision making and b) aggressive me-only thinking. reducing congestion would reduce travel times (thus emissions) and high emissions produced during constant braking/acceleration cycles.
I think I'd fall asleep if the ride was longer than 10 minutes. What are they proposing to do when your car is automatically unloaded and you don't drive away?
So if monorails are so great, why aren't there more of them?
A multitude of reasons can explain why you don't see monorail selected for rail transit needs that often. One recurring theme we've heard from experts over the years is quite simple, a lot more people can make a lot more money if light rail or subway is built. The conventional rail industry has established a stronghold and monorail is discouraged by consultants. We have many news clippings where falsehoods were openly given to help defeat monorail. There are behind the scenes efforts against monorail as well. This continues today. Paranoid you say? If you study the subject long enough, a pattern becomes as visible as a light rail train hitting a car. We'll continue to point out the advantages of monorail to battle the mistruths being circulated. Our frontline for informing people about monorail is the website. Please help us spread the word!
Nash thought of this during the late 50's/early 60's. If you take a look at the Nash designers sketch book, available in the automotive section of Barnes and Noble or Borders book stores, you'll see this suggested in a sketch of a Rambler riding on a rail.
because I hit submit a little too quickly...
robotic cars, at a minimum, would produce better fuel efficiencies the same way that cruise control does.
try it some time on a long trip. cruise control is better at maintaining constant speeds and gives better gas mileage. humans have a tendency to speed up or slow down without noticing (we're highly distractable) then brake suddenly or accelerate to compensate. we make crappy pilots for mundane/repeatable/non-creative tasks which is where machines excel.
other "environmental" benefits would be reduced loss of life. maybe not environmental in the classical definition... that benefit alone is worth the price of admission. no more drunk driving deaths.

Seriously, this morning it was about 20 F ( -2 C ) with slippery, new fallen snow on the ground. No one was going past 55 on the expressway (normal speed of 65). Living in upstate New York, bicycles are impractical many times a year.
As a kid I rode in winter, but it was dangerous enough that I took old tires and stuffed them with newspapers and embedded nails in them to get a grip. It didn't work.
My favorite link for this sort of thing is this PRT page. (And on a side note, I think hanging the cars makes more sense than riding on top of the rails). It's a good idea but it will take some getting used to, and will require mass-production to become truly cheap.
A finite resource will always be completely consumed so long as there are no limitations on the consumption of that resource. A resource in short supply becomes expensive, while a resource in good supply becomes cheap, and a resource in oversupply is still snapped up by anyone who thinks they can use it.
This is true of transportation as well. No matter how much road you build, someone will always find a way to use it. The only limiting factor is that people don't like to travel for more than an hour. When highways are built suburbia springs up around them. When the Long Island Railroad was built, the areas around the stations w/in an hour's travel quickly became heavily developed. Building roads does not make travel easier - it just enables more of it. Thus the most important factor in a transportation system is not how much it can carry, but how well it performs at peak capacity. Railroads, and presumably PRT, may become crowded the traffic continues to flow. But auto roads perform miserably above a certain traffic level - some sort of breakdown always occurs and brings huge chunks of the system to a standstill.
The first key to making PRT a reality is to make it effective enough and cheap enough to allow near door-to-door travel as fast or faster than cars. If people have to take a car to get to the PRT station, they will figure that they might as well drive all the way to their destination. The second key is to make the system strong and flexible enough to allow changes in how it is used (like cargo transport, and automatic delivery).

I used to live in Cardiff and it would be well suited for this facility. I see that it's proposed to link the city centre with the former docklands that have been redeveloped as "Cardiff Bay" but suffer by being a good mile and half from the centre with poor public transport links (memories of waiting at Cardiff Bay station late at night whilst the local kids trash it and hoping the train will arrive before they decide to trash me as well).
What's more, for political reasons, the National Assembly has half its operations in the centre, and half at the Bay. and currently has to run a dedicated bureaucrats' bus service between the two during the working day.
The turn up and go aspect would have been ideal for me when I was working in the Bay. No more relying on Valley Lines deciding whether or not to bother to run a train!
CPRT is an organization dedicated to promoting these kinds of transportation systems, and Taxi2000 is one commercial system being developed. The washington.edu evaluate many different systems.
Note that it is essential for these kinds of systems that cabs are small--if they hold many people, they either need to stop a lot (=longer travel times), or they waste a lot of space and resources.
Bruno Latour has written a very detailed, book length treatment of a similar (point to point light rail) project called Aramis (also the name of the book) which was under development in France for quite a long time only to die ignominiously with its resulting technologies scattered into more conventional rail systems. Despite the book's irritating (to me, anyway) seminovelistic style, its attention to detail and thought-provoking treatment of the relations between social and technological factors in the project make it a very worthwhile read, if you care about that sort of thing. peretzpup

. A true replacement for the car!"
A true replacement for the car?? It is still a car.. you just have less choice of where you want to go because once you leave your house, you can only ride on the tracks and only go where the tracks lead.. this doesn't seem like a good thing imho..
In modern times, normals cars are increasingly making less and less sense: it's too easy to get in an accident, to easy to get lost, and cars are for some people just plain inaccessible (some types of handicaps, children, etc).
A system like this alleviates all these problems. Of course, it ahs problems of its own: It has to be easily expandable so that new destinations can be added. It needs to be crash-proof (or at least moreso than normal cars). And possible #1, there needs to be some easy way to transition from the current mode of transportation to the new one. People still own very expensive cars and probably won't want to give them up, and until this new system is completly implemented, there will be places which are inaccessible from it.
Oh well, if the transition can go smooth, and the system is relatively bug-free -- maybe the cars could run on a Linux kernel ;-) -- it's a very, very smart idea.
The United Kingdom has a population of around 60 million people, with 241,590 sq km of land.
That's a population density of 241 people per square Kilometer.
source
The Continious 48 states have an area of 7.7 million square Kilometers, and a population of around 285 Million. That's 37 people per square kilometer, on average.
About 1/6 the density of the UK.
So that means in any given area in the United Kingdom, there are 6 times as many people there to use public transportation, making investing in public transportation far more economical, and also making it economical to run efficient, timely connections to just about any place one would want to go.
In the United States, because we are so spread out, for most of the US, there are not enough close points of interest to make it feasible to build usable public transportation. Where the population density is high in the United States, such as New York, Boston, Los angeles, or a number of other Cities, you have an advanced system of public transportation that would rival anything in Europe.
But outside of that, there just aren't enough people in the right places to make a good system.
That is why we are so hung up on our cars. Because we, for the most part, can not build a public transportation system that will get us where we want to be, when we want to be there. The economics just aren't there. I'm sure in most of the UK, you can get anywhere you want by PT within 15- 20 minutes of when you want to be there. Here, except in cities, if there is public transportation, it will get us to our destination within 40 to 120 minutes of when we want to be there.
Would you find that acceptable?

What an idea. We take peoples car's away and replace them with these other cars. But the new cars run on tracks sort of like trains instead of the far less expensive roads that we currently have.

- Raytheon in Marlborough Mass. is a closed facility.
- The prototype was considered a failure.
- It was disassembled several years ago.
- The architecture Raytheon was using had long ago been proven inefficient in professionial transportation engineering circles.
- This was to be one of those swords-to-plowshares "Peace Dividend" stories. Instead it was remarkably similar to when Boeing Vertol stopped making helicopters and attempted to build LRVs (ask Boston's MBTA what they're like and about the court settlement.)
Unfortunately this poster is absolutely classic of so many of the alternative transportation folks: Short on details, wrong on facts, and prone to handwaving aside problems - the exact same problems that hamper existing systems. With supporters like this no wonder the field hasn't progressed markedly in 30 years.I don't read ACs: If a post isn't worth so much as a nom de plume to its author then I wont bother either.
The most comprehensive info on PRT is available at Jerry Schneider's Innovative Transportation Technologies site in the section on Personal Rapid Transit (PRT). The site has a much broader scope and compares PRT with several other systems as well.
I wonder, however, whether in urban areas (where most transit trips occur) this makes sense. Where's the cost savings over more traditional services like light rail and buses? If subject to large volumes of people, this would quickly be overwhelmed, while light rail vehicles that can hold 150-200 people wouldn't have that problem.

What we need is less moderation and more free thinking.
My real account keeps getting labeled as a troll...
The technology used automobile-sized cars that could follow each-other at a less-than braking distance whenever they had to run on the same track.
Needless to say, the complexity of implementing the required movable block technology proved too much for the researchers, and the whole idea was scrapped.
The first thing I wondered is about crime. The picture on the BBC story seems to show a person entering a car that already has passengers. Could, say, a mugger get into a car carrying my wife? It would seem to be a pretty safe place to commit a crime, as compared to, say, the subway with other passengers or a bus with a driver.
The paper actually addresses this and points out that there are short wait times for cars, and that they will have security cameras, and that a central control will be able to bring the car back home for repairs/cleaning. Importantly, it also implies that riders can choose to ride alone, but it does not say whether this is the default behavior.
And that is exactly why it works well in urban areas, and in fact promotes urban growth and reduces sprawl. In the city people routinely choose to live near the bus or subway because it's much more convenient than driving a car. Even out in the burbs, the recent growth of "transit villages" where you can buy a condo walking distance from the subway is a sign of people's preference to avoid traffic.
On your other point, mixed flow of transit vehicles (of any kind) and autos is bad because it's much SLOWER than a dedicated right-of-way. The idea of taking the cars off the track into normal traffic seems pretty inefficient to me, for that reason. Of course, if you're way out in the sticks, no traffic, but then also no critical mass to support the transit system.

Cry me a river. I rode my bicycle to work today (as I do every day), in Minnesota. The temp was 13 degrees F. Not a problem with proper clothing (a hat, windbreaker, and warm gloves). I live in the city, where traffic on major roads keeps them clear enough that I can travel the 3 miles to and from work faster than a car can.
Sure, I slow down on the back streets that aren't as clear, but it's easy to get most of your miles on busier streets.
Apparently you have no clue what roads cost to UPKEEP. The initial investment on rail is high, true, but the upkeep is a fraction of that.
The Free desktop that Just Works
My morning commute is about 15 miles.
Why is it automatically assumed that high-tech is the solution to every public problem?
I just got back from visiting family in Wroclaw, Poland - the trams there are old, a little dilapidated, and date back to the 50's. But they work, dammit! There's track everywhere, trams run every few minutes, the network is extensive, and it's *cheap*. You can get anywhere you need to go in 15 minutes or less.
I'd consider biking it. Instead it's about 15.
All of these have a disadvantage, but it is a system that exists now in most European cities. Even some UK cities are reintroducing the tram now.
However what really makes it work in Europe is the integrated transport policy which links the different types of public transport together.
What is discussed here is a blue sky project for te distant future. It may be created in some new purpose-built 'city' like Milton Keynes, but otherwise creating that network of lines would be a nightmare.
Just using a mixture of conventional public transport technologies can reduce road loading by an incredible degree. Having a policy of integration means that I can use different types as a simple way of getting from A to B.
Here in Germany, I can hit the web site of the transport system (it is also in English so have a look) and it can give me the right mixture of trains/trams/metro/buses to get between A and B throughout the region.
This isn't rocket science, but perhaps if we could drag the UK's tansport system to the level of other major European countries, then we can start to look at more radical technologies.

Bring back the old version of slashdot.
Ah, PRT, the future of transportation. West Virginia University has had it's own PRT (Personal Rapid Transit, also known by the students as Pretty Retarded Train) system since the early 1970's. The PRT serves as the primary mode of transportation between the two main campuses for thousands of students every day.
In fact, this morning I was riding the PRT to my CS lab, when I experienced first hand one of the minor glitches in the computer system that controls the PRT.
The computer system is still the original one from the 70's, housed in a warehouse-like building, mainframes with magnetic tape reels and all, running programs written in Fortran by the engineering students that built the thing, with all the processing power of the average digital watch.
Anyways, the PRT car I was in was right in the middle of the long straight stretch, having reached it's top running speed of about 40 miles per hour, when the power went out. The little electric cars are designed so that when the power goes out, the wheels lock up.
So, our PRT car goes from 40 mph to a dead stop in under 1 second. I was immediately reminded of physics class; objects in motion tend to stay in motion unless acted upon by an outside force. I was standing up at the time. Fortunately, the outside force acting upon me was the soft and squishy back of the person in front of me. The people sitting in the front had the less pleasant experience of having their faces acted upon at 40 mph by the front plexiglass window.
So, yeah, PRT all the way!
All that we see or seem is but a dream within a dream.

local legislatures will never allow this to happen,

I recommend that anyone interested in PRTs read the book "Aramis, or the Love of Technology." It is mentioned in the paper which the article links to.
Aramis was an attempt to bring PRTs to Paris, and while the paper says that the problems resulted from trying to fit the system to an urban environment, I got a distinctly different perspective from the book.
Basically, the problems involved the incredible computer-related difficulties in the system (which may be irrelevant at this point), and the fact that the frequent stations combined with track would result in a huge amount of space being used for the infrastructure.
Another problem that was discussed was safety, and not safety in the practical sense, but in the political/legal sense. Apparently, there was great difficulty finding a way to guarantee that the system would be secure enough.
In the end, the result was that the numerous delays caused by technical problems, combined with political issues, pretty much sealed the fate of the system. However, what the book dwells on rather excruciatingly is that technology is not separate from society. One of the main reasons why the book was written was to demonstrate that no single factor killed Aramis; rather, it was a confluence of factors.
For this reason, I have taken proposed PRT systems with a grain of salt ever since. Yes, there are test systems, but they don't experience a serious passenger load.
We pour billions of dollars into public transit that never pays for itself. This sort of thing works fine in cities where people are packed together such as London or NY. These cities were designed way before the car was invented--these cities were built where the populace living and working in the city.
Now look at the newer more sprawling cities. There is no practical way to have public transportation. If I want to go somewhere besides downtown, I would have to drive to the park-and-ride and take the bus to downtown and transfer out.
I can't even get to my work on the city bus because I work in another COUNTY. We use to have a vanpool from my area, but I would have had to drive half time it would have taken me to get to work in the opposite direction to get to the parking lot where they met.
Fortunately now I'm in a 3-day a week telecommuting program.
What we NEED is not just the focus on public transport, but more fuel efficient/alternate fuel cars, better roads (sitting in traffic causes pollution too!) and more encouragement to companies to have employees telecommute.
If you've never been modded as "flamebait" or "troll," you've never tried to argue a minority viewpoint here!

Monorails aren't anything new, but their design is pretty modern (compared to "light rail.") Why are we constantley reinventing the wheel when we have a cheap (cheapest elevated transit,) quiet, and environment friendly alternative that has been around for ages. I only wished that we could see more monorails in America. Light rail has done nothing but wasted money. Monorails can fit through dense areas and don't have to stop at traffic lights like light rail does. If we want public transit to be a better alternative to cars, we're gonna have to put it in the air (as in elevated.)
If you want to learn more about monorails I would recommend checking out <a href="http://www.monorails.org/" target="_blank">www.monorails.org</a>

The mfg and wharehouse industries have used a similar system for years. When I worked as a design engineer we had robots that you could tell to get _____ from _____ . We had a lot of these little guys running on tracks embeded in the cement floor. We had few problems with them as they were not exposed to the elements,senses their surroundedings(people), and didn't drive themselves thru the wall like the forklift driver that came to work drunk.
Wouldn't it be neat with a pair of breaks on these babies? I'm concerned about people or animals who accidentaly may stumble into the track. Since there's no driver, I guess everyone inside are distracted talking to each other or reading a newspaper. In a car you have the driver who (at least tries to) control the vehicle.
Early on transporation within urban areas was accomplished on a bicycle. Along came trolleys, then cabs, then the bus, then everyone had their own auto. When the US had a opportunity to build a rail system (realistic, as opposed to many of the fanciful and doomed ones built by the empire builders) it put the money into interstate highways (actual motivation: national defense, a means to move arms around fast and regular stretches required to be straight for a distance in the event they'd be used as runways) We're living the legacy.
A feeling of having made the same mistake before: Deja Foobar
Future versions may have dual control to allow people to drive the cars from the nearest station off the track to their homes.
Now that's something I could buy into. Public transport is great and all, but the problem has always been (at least in the US) that once you get to your stop, there's still quite a ways to go. Also, Americans in general just plain and simple don't want to give up the mobility of having a car.
Personally, I live near Atlanta, GA. We have the MARTA trains to move you through the city. The only problem is, the city is huge, and MARTA has maybe a couple of dozen stops thorughout the city, and it doesn't even span out to where I live. The result is if I were to take the MARTA anywhere, I'd still end up travelling 2-5 miles, sometimes more, to my final destination. That's just plain useless.
Being able to drive your car onto a public transportation grid that would take control and send you whisking off to whatever exit you chose would be great. I don't know how it would handle tremendous volumes, but if they can get the process down pat I would be one of it's biggest supporters.

The dual control aspect is the part I find most interesting.
One of the big wastes of the car industry is the amount of time all the capital (i.e. the cars) is being under-utilised. What percentage of time does a car sit on your driveway?
This system has the potential to turn into the ultimate shared car pool.... you can use them as public transport, but if you needed a car you could just switch it to manual and drive wherever you wanted, paying for use by the minute or whatever. When you'd finished, you'd just have to drop the car back onto any point in the network and it would wander off for someone else to use.
Would present some interesting technical challenges - the system would have to adapt to cars being dropped at any point in the network, and also dynamically move cars around so that there were enough units in the areas where demand is high. You might have to give it special warning in the case of major sports events or public gatherings, for example.
Britain is not still in the Middle Ages. Like its former colonies (the United States, Canada, Australia, New Zealand), it is a land where immigrants are coming in for a chance at a better life, businesses are secure under a good (British) legal system, and people are free to elect their own leaders.
Despite those laws about nobility that you cite, the ruling elite have no more special privileges than the ruling elite of the United States. For example, see how many laws specifically do not apply to the Senate.
Like it or not, the United States was born of British parentage. And the apple did not fall far from the tree.
Places like North America that already have a huge transportation infrastructure would find it expensive to implement one of these, good to see that some European countries are testing them out now.
Yeash... Beecoz over hear in backwardz Europe Me and Igor are still travelling on Donkeys!!
Actually, the state of the railway system in England today isn't far above a donkey network. A donkey network would probably have less shit on it.

Actually, the paper at http://atg.fen.bris.ac.uk/picet.htm makes it clear that the costs will be one quarter, and the safety ten times as great. Read before posting. Idiot.

This is a very interesting scheme. I notice from the article, that other UK cities which have Tram systems are mentioned (Sheffield for instance).
I also notice that the inventor of this system is a professor at Bristol University. Now why isn't this scheme being implemented in Bristol rather than Cardiff? (Bristol and Cardiff are very close to each other) Could it be because Bristol City Council still refuse to do anything meaningful about transport within the city, for which there is no short-term political gain? Bristol has been crying out for a tram system, or a light rail system for years now, but nothing ever comes to fruition in spite of all the talking.(I know this because I live there). The fact that a professor at the cities University implements a ground breaking scheme in another city speaks volumnes about what's wrong within Bristol.
Why to you is it?
{begin rant} Simple (at least for me) -- SUVs excessively threaten me as the driver of a normal vehicle.
How?:
1. excessive weight and energy -- my car is 3000 lbs gross, while a suburban is 8600 lbs (http://www.chevrolet.com/suburban/engine_sub/8100 .htm). So, the suburban is carrying more than double the energy in a collision.
2. high bumpers, which conveniently miss most of the crumple zone of my vehicle, magnifying the hazard of the excess weight of the SUV.
3. poor handling relative to a normal vehicle, which increases the chance of a collision.
4. SUV drivers with no clue as to how to handle these limitations.
5. the fat, tall, and opaque behind of an SUV blocks my view of potential trouble ahead.
6. I observe that SUV drivers are more prone to poor driving -- Left Lane Banditry (failing to keep right except to pass), and wandering all over the road whilst Driving While Yakking/shaving/reading/disciplining their rug rats.
I would mitigate these hazards as follows:
1. SUV speed limit is 80% of the posted limit (limit 70 mph -> SUV limit of 56), which reduces the crash energy by 36% (one half m v squared.) Ban SUVs from the passing and HOV lanes.
2. tax SUV owners on a per mile driven and per pound basis, to compensate for the increased wear on the road. Heck, tax all drivers this way.
3. SUV owners pay $2000/year/SUV into a SUV victims fund.
4. remove the business tax preferences to SUVs.

The whole idea of tracked personal transit is a futuristic idea that's obsolete. We're far enough along in computing that automatic driving in a controlled environment is quite feasible.
I once thought that the place to start was with automatic driving of empty rental cars. The idea was that you drive to the terminal, get out, leave the rental car, and it slowly drives itself back to the rental car lot using a dedicated lane. This would save travellers about half an hour per trip. The next step would be to extend the system to arrivals, so there's a car waiting for you at baggage claim. Then get major hotels, convention centers, and parking garages on the system, for automated valet parking.
But if you crunch the numbers, it would be cheaper to hire minimum-wage people to do that job.
It also solves the problem of the stations not being nearby - just drive your car to the on ramp, sit back and enjoy the ride. Until the exit comes and you have to wake up, of course.
Was that out loud?
Virginia Tech has a project within the ongoing Virtual Corporation class called PERTS that sounds just like this and has probably been around as long as this project in the UK (http://www.perts.ece.vt.edu). Does anyone know if there's a connection between the two?

Stupid people suck.
how about requiring they meet the same emission requirements as cars as well?
Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.
And do you want to take an hour driving to work in the morning at 5 mph? Thought not. Learn to understand that you are not alone on this planet, that you gain from cooperation, that that you are not stuck in the trafic jam, you are part of the trafic jam. Then we might begin to solve these problems, and you might get something better than what you have now.

The US can't properly fund it's national rail system.
Heck, New York can't even properly fund it's subway.
Autos have a stranglehold on the US.
I have a small 4cyl pickup (you can find it under misc pictures on my website if you're curious) which gets about 25 mpg on a good day and I drive ~38 miles each way to work. The truck was used and cost ~$13,000, expected life ~5 years at the rate I'm putting on mileage. @ 72,000 miles I just put $1K into repairs, as it ages this will happen more frequently due to regular maintentence combined with parts life expectencies met.
Prior to this I had an '86 T-Bird which I piled 273K miles on, with other vehicles (including a very forgettable Fiero) I've typically been stuck with at least 30 miles each day of driving.
At 1.25 per gallon, ~22 mpg, and avg mileage, cost of gas, per year ~$450 (actually more than that now, about $2000 a year)
Cost of truck amortized over 5 years, $2,600 per year (straight depreciation)
Tires, oil, repairs, figure ~$1,000 per year
Time I have to sit and drive my commute, unable to do anything else, ~500 hours per year, figure my personal time is worth $10/hr, and that's $5000
Total cost per year: ~$9000 per year, for which I must earn ~$9000 just to pay the expense and taxes for the actual costs (not including personal time)
Even if I could get these costs down to 2,500 per year, I'd still spend enough to finance my own spur on light rail in a few years, excluding interest I've lost, etc. Watching to flow of traffic on the main commuter routes in my area, I'm hard pressed to believe we can't run a light rail most of the distance, yet, people still would fight the tax. If we had that system the truck would probably accumulate less than 3,000 miles per year (shopping, vacations, visit friends, etc.) the way my T-Bird did for the 3 years I could walk to work.
A feeling of having made the same mistake before: Deja Foobar
I want less infrastructure (less taxes) not more. I want fuel-efficient vehicles (hello Honda!) not electricity-driven public transportation systems (burn petroleum in central station, then carry the electricity 20+km to train), I want freedom to go to Vegas at 4:22 AM, when I FEEL like it, not because it's convenient on the bureaucracy-mandated "she-dule" (skedual for US speakers).
I want convenience, and low cost... In UK, gasoline is out of this work, but in US, it's not, so no public transportation for me.
What? our freeways are congested? So what. telecommute, move minutes from your job. there are many more, better alternatives. But the fact is, you have the choice. With Public transportation and high taxes, you lose the choice, becuase you're GOING to get taxed, so you might as well use it, even if it's less convenient.
"Piter, too, is dead."
Instead, how about a fleet of preprogrammed robotic Segways?

That is an incorrect assumption! The benefits of a well designed and implemented mass transit system are much more far reaching than solely to the individuals actually using the system.
And just where might this system be?
The only and best known cases of mass transit that work are the ones where there is absolutely no other choice that can be made. For example, access to downtown New York City is impractical in most motor vehicles. The transportation models for motor vehicles don't scale to that density. Everyone uses public transportation not because they want to but because nothing else works. But I live on a farm, not New York City. Their solutions don't scale to me either.
And also, before you continue on your anti-SUV line of rant, consider what vehicle options a family of five should use: No, I don't have enough room in an econo-box for my wife, an aging mother in law, and two small children in child safety seats. Our alternatives are 1) two cars, 2) a minivan, 3) a large sedan or station wagon, or 4) an SUV.
Options 2, and 3 have similar efficiencies. Option 4 is only slightly worse, Option 1 is simply impractical. Just so you know, my wife and I chose option 3.
Believe me, I'd drive a smaller vehicle in an instant if I thought it were feasible. But it ain't gonna happen for many years. Neither is it likely that I'll see any form of public transportation out where I live.
You talk about squandering natural resources. Ever study what it takes to run a city? Ever really wonder whether there truly is an economy of scale there? Well, I suspect you won't like the answer.
Before you go green with stupidity, think. Think about how mass transit works when you're carting around three or more dependents. Think about what a mass transit system is supposed to do during off-peak hours. Yes, cities may have economies of scale, but they also have the overhead of distribution systems. And if that's not enough, think about failure modes.
Clearly the guys who wrote the article believe in autopilots. That's nice. Do you trust your neighbor to maintain this autopilot so that it won't fail catastrophically? How about the instrumentation that feeds it? Clearly when even one such control system goes wrong the consequences are far greater than if just one idiot runs a red light.
Don't think you can coerce your neighbors to use what you use. Successful systems work because they appeal to everyone. SUVs appeal to many families because there really isn't anything with the safety and capacity that these things have. Yes, I'd like economy too. But which features do you think are more popular?
Enjoy your nice haven in the city. Just remember what supports it, and remember that yours isn't the one and only way of life.
Nearly fifty percent of all graduates come from the bottom half of the class!
Yeah, I know lots of folks like that. The interesting bit is that none of them have ever tried using the bus.
Don't mistake me for one of those gung-ho transit people--I currently drive to work because it takes 1/5 of the time it would take on the bus (I reverse commute so existing routes do not adequately serve my needs). However, I used the bus nearly every day from summer 1999 to spring 2001. I enjoyed it very much, and even used it for purposes other than going to school--it was handy for trips downtown on the weekends or to the Target Center for a game, etc. No hassles with designated drivers, ya know. People of all kinds ride--from executives to students down to your token bag lady and/or drunk.
There are a substantial number of people around here who are desperate to use the bus. All you have to know is that when a new Park-and-Ride out in the suburbs opens (let's say there are 900 parking spaces) it's full to capacity within a couple of weeks.
It's too bad, really, that transit has a largely undeserved reputation for the kinds of things you mentioned. I always found the people on the bus very friendly, with probably less then 5 exceptions over the course of two years and hundreds of rides. All I'd say to the people who don't want to be 'contaminated' by the smell, appearance, and behavior of real people is: you better just stay in your homes, because (GASP) these same people are at your grocery store, walk the streets of the city, etc.
Somehow the idea got into people's heads that the smelly people, the drunks, et al. are only on the bus to accost other people. Nonsense. They just want to get from A to B like all the rest. OK maybe it happens sometimes but the drivers won't take crap from anybody...if someone is disruptive they'll get kicked off the bus, simple as that.
I do own a car in the city...
But like most people in the city, i take public transportation.. it's just not practical most
of the time to drive into the city. specially to go to work.
Step in to a nyc subway, and you will find ALL parts of the economic spectrum.. From homeless,
to CEO's
So, it is possible to have a widely accepted mass transit system. You just HAVE to make it NEEDED, USEFUL , and RELIABLE.
( although after the damn 2 train became local, I don't know if I'll stick to the damn reliable part
Okay, here's the deal... the reason Americans can't live without their cars is that their cities are built around the idea of the car and can't operate efficient public transport systems because of their 'shape'.
There's an interesting intersection of transport, urban theory and economics going on here. I did my graduate architectural thesis on the design of transport systems and got heavily into the topic.
The structure of most major European cities was built before and during the 19th century, a period when the options were to walk to work, take slow (relative to today) horse-drawn public transport or, toward the end of the century, cycle. This had a major effect on the shape of European cities - it lead to high density urban settlement, since most people will try to minimise the time it takes them to get to work, particularly if you're working a 12 hour day plus a half day on Saturday, which wasn't uncommon 150 years ago.
From the end of the 19th through to the first half of the 20th century, as the technology of transportation improved, we got electric trams and various forms of railway and buses with internal combustion engines. These modes of transport changed city shapes somewhat, with ribbons of suburban settlement spreading out in spokes from the early and mid-century core. Commuterland was born.
What's important to note here is that commuter flows in this setup work like river systems draining to the city centre, with walking feeding to buses and trams, then to railways - each level an increasingly heavy capital cost, but since the volumes of traffic rise, they're still economic to put into service and maintain. Everyone's moving along the same routes from one easily defined location to another to planning mass transport is relatively simple.
Let's contrast this with the younger cities of the US, which have mostly flourished since the 1920s and in a period when low-cost personal transport has become available in the form of the automobile.
With a car, you aren't limited to moving along the routes defined by public transport systems. You can go from anywhere, to anywhere, at any time you choose. That's why the automobile has been so spectacularly successful in the 20th century. Using a car, you can live in one suburb and work in another making a daily journey which would be very awkward with a European-model public transport system. You'd have to go into the city centre and back out again.
Automobiles induce people's journeys patterns to flatten and begin to lose their geographical structure. Over time, this has an effect in the very structure of a city - shops and places of work can be almost randomly located miles away from homes and all three can intermingle and recombine in many permutations. The American romance with the block/grid system of urban planning embodies the neutral network of the car perfectly in contrast with European organic urban planning based on patterns of historic use, travel and topographical incident.
When a city is structured so that any given node practically has the same importance as any other, providing a public transport service to meet what is now nearly a random walk becomes impossible from an economic point of view. You'd have to run lots of very small buses criss-crossing the city at close intervals - the bus turns into a taxi service. Traffic congestion makes bus timetables a point of humour anyway.Railways are redundant since not enough people are making journeys along their high maintenance-cost fixed routes.
So, with the rise of American cities coinciding with the rise of the internal combustion engine, public transport had much less opportunity to help build the American city and make itself useful to citizens. The car has shoe-horned out any competition by shaping the city to its own patterns.
Of course, the car brings its own issues: it's a fiendishly inefficient use of finite energy resources (still mostly derived from carbon-rich fossil fuels or nuclear fission, even if the car is powered by electricity). Big retail parks (owned by national and international chains) have persuaded you that you should be spending your own money distributing goods you have purchased instead of having them delivered to a local shop, which has gone out of business. If you live in a modern suburb it's possible that a shop that's in walking distance never existed. People without access to personal mechanised transport find it increasingly difficult to perform their daily tasks. You have to devote a chunk of your income going to the gym regularly to make up for the exercise you're missing by not walking or cycling...
Anyhow, that's how I see "Why are most AMERICANS so hung up on their cars?"
11.6 miles.
$675 million. Half comes from the Federal Transit Administration, another $50 million from a federal CMAQ grant. Rest from various state/local sources. The biggest chunk pays for the extraordinary tunnel project under the airport.
It's not meant to benefit anyone in particular. It's meant to provide people with options. Yes, not a lot of people at the moment. The hope is for the line to become part of a regional transit system (including the Dan Patch corridor, Riverview, North Star, Hwy 61 corridor, etc.).
You're judging it with a time horizon of only a few years. It's an expensive project, but viewing it with a 30 or 40 year perspective and assuming the development of a network, it will be quite different. That's all rather optimistic at the moment, however.
Don't get me wrong, I'm not a huge fan of it. But that's the thinking, at any rate.
One of the issues is trying to match transportation solutions to the problems. This idea has been around for a long time and would require building a new set of roads(guideways). Then ppl will want them all over. Roads are useful for local commutes. Instead, Money should be thrown at medium distance/medium speed solutions. Something that is > 100MPH or 150KPH. Check out highspeedmonorail.com. This was meant as a monorail for colorado that our governer fought against. It is designed to travel in the range of 100MPH - 250 MPH. This makes it useful for transport of ppl at 30-200 miles away. A 200MPH monorail is useful for cargo transport, esp, during the nights.
"A true replacement for the car!"
A true replacement for the car will have to be capable of brakestands, wheelies, donuts, and sub 10-second 1/4 miles.
Tell you what, take your assumptions and prejudical remarks and, and, and... --Make them in to yet another post worthy of an ignorant Slashdot weenie.

Nearly fifty percent of all graduates come from the bottom half of the class!
Simple (at least for me)
Bingo. And that's the point I was making. That's how you'd do things in the land of mr_death. There are tonnes of things on this planet that personally annoy the hell out of me / I find downright retarded. The list is looooooong and varied, and I could also come up with a justification for how the elimination of each and every one of them would improve society.
Unfortunatly there are those folks that have the very same attitude about things that I like doing. They can also come up with some justifications for why I shouldn't be able to do the things I enjoy doing, and I think they're full of shit. Its a free country folks (or it should be free as humanly possible) and with that freedom comes the realization that some people just aren't going to do the things / make the choices / like the same things we like...
Now, for the things you'd do....
1. SUV speed limit is 80% of the posted limit (limit 70 mph -> SUV limit of 56), which reduces the crash energy by 36% (one half m v squared.) Ban SUVs from the passing and HOV lanes.
Lets lower the crash energy of every vehicle while we're at it. Lets lower the speed limit to 5 MPH, and lets have a law that states all autos must be proceeded by a guy waving a red flag to warn others he coming (this was an actual law at one point). I guarentee accidents would plummet.
2. tax SUV owners on a per mile driven and per pound basis, to compensate for the increased wear on the road. Heck, tax all drivers this way.
So, you're willing to give up your privacy to allow the gov't to track everywhere you've traveled? Remember, if we're compensating for the wear and tear on a road they're going to need more than simply milage. They're going to have to know where you've gone so they know who to compensate. Of course, we could just make each and every road a toll road. That would solve the problem as well. Hope everyone has a lot of quarters lying around. Then again, we could all use speed pass... but then the gov't is tracking us again.....
3. SUV owners pay $2000/year/SUV into a SUV victims fund.
And lets make every male driver between the ages of 16-25 pay into a fund as well, considering they cause the most accidents in this country... oh, wait a minute, they already do... it's called insurance. The wonderful thing about those money grubing bastards in the insurance industry, they don't like paying out more money than they take in. The second they find statistical evidence that SUVs (and SUVs alone, they control for the usual supsects: age, gender, marital status, past history, etc...) are causing them to lose more money (due to claims) than any other vehicle you can bet your bottom dollar that rates on SUVs are going to rise (if they haven't already).
4. remove the business tax preferences to SUVs.
That's (AFAIK) because they're classified as trucks, not cars. A bit of a dodge I agree.
We Europeans are 50 years behind in development, or what? Well, I guess I can contribute with one of my own prejudices:
Everything's big in America. Wide roads and huge cars. Every American town looks the same, with those typical suburban areas with straight roads and big houses (and barbeques in the back yard). In Europe, on the other hand, we have to shape our cities to make them fit alongside mountains, rivers and coastlines. No two European cities look the same.
I don't mean to be arrogant, this is my impression of North America. I hope I'm not right.
My point (which is the exact opposite of Rackemup's) is that a transport system like the one described should be much easier to build in American cities than in Europe. (I'm thinking of the stereotype American city which just grows as big as it needs to be, as opposed to European cities that are formed by the terrain and restricted by thousands of years of history.)
Wow.
You have some serious issues, and I would recommend you not driving anymore if you have this weird mind set that SUVs really are all that evil.
Please actually back up your claims as to SUVs being so much more dangerous and causing more accidents. I see many more smaller passenger car accidents than SUVs. I'd look up statistics because I'm confident you are wrong, but I'll leave the burden of proof to you since you are the one making wild accusations.
As for point 1, there are a few places who have 'Truck' laws in which SUVs do qualify where you cannot drive in the far left lane and have a seperate posted speed limit. This is mostly due to commercial vehicles (semi-trucks) which are much much much more "dangerous" than any SUV you've seen.
Onto point 2, Do you even have a drivers license dipshit? Did you ever look at the little forms that DMV has all over the place explaining where the DMV fees go? Have you ever wondered why licensing fees go up for trucks, and other luxory vehicles?
And, the most innane point, #3. SUV victims fund? Are you joking? Nobody made you get a car. Nobody made you drive it. The only victims in your twisted scenario are the people reading it. I have been hit by 3 cars, neither of which were SUVs. I have been in about 5 car accidents (all rear-ended while I was at a stop.. go figure, bad luck) neither of which were SUVs. Worst was a truck used for business purposes, and that was only bad because he was going 55mph when he hit. I don't care what type of car you drive, if you hit a stationary object at 55 it's gonna screw the other person. The only benefit in the whole situation is his car was mostly ok from it. I say more power to him.
I've already wasted too much time, but every argument you posted except #4 was just absolutely stupid. Do yourself a favor though, and take mass-transit, because it obviously stresses you out way to much to have all those SUVs stalking you and just waiting to make their killing move.
Dacels Jewelers can't be trusted.
You're ringing my bullshit detector. :)
So, a reference please for the claim that per-capita energy use in the US is higher than other countries.
I researched this a few months ago and determined that, counting only first-world industrial countries, at least in terms of electrical usage, Americans are about in the middle. Some Europeans use more electricity per person, others use less.
I also saw that electricity usage per GNP was somewhat lower in the US compared to several european countries.
Numbers for GNP, electricity usage, and population were taken from the CIA world factbook, 2000 edition, then divided with a calculator.
Please cite a source for your claim.
There was a study a couple years back that showed less intelligent people are more likely to breed than the more intelligent ones. My guess is that you're classified within the former.
1) You contribute to the overpopulation of the world.
2) You drive (I'm assuming) some type of minivan or SUV, thusly damaging the environment with extreme amounts of pollution.
3) You obviously don't know how to distinguish between one person's opinion and hard fact.
4) It doesn't even seem as if you've looked into other options. Get your family's collective lazy asses off of the couch and go for a bike ride together.
Yes, I have to take issue with this statement: Finally, I doubt that it could be economically implemented anywhere on earth, as buses and trains are cheaper because they use economically feasible infrastructures (existing roads and tracks) , and many more specially designed small cars would have to be designed and built from scratch. Of course that's silly. Everything had to be built from scratch at some point.
Also, Pittsburgh's culture supports individuality. suggests that public transport somehow impinges on individuality. It doesn't. By efficiently getting people where they want to go, it supports individuality, and this personalized system seems to do better than others.
Lies about crimes
Anyone remember that book? It may have been his first.
As for issues of personal security, consider the following:
The service is demand driven, so that when you arive at the station, you take the first available car to your destination. during peak periods there may be some waiting (usually less than 2 minutes), but during off-peak times (ie late at night) there will always be a car waiting for you to board immediately
The stations are small, well lit, and monitored by video cameras (the Taxi2000 concept recommends continuous video buffering, so that if a security person monitoring the situation spots a problem, the last few minutes of recorded video can be permanently stored for evidence). There could also be similar cameras in the cars.
Each car will posess both a button to cause the car to stop at the next available station (to allow a quick get away) and a button to take it to the nearest police station (which overrides the first button).
Each of these features would make it difficult to get away with any crime committed on these vehicles, and together would form a good psychological deterent to anyone considering something illegal. You'd probably be in more danger walking to the parking lot.
Everything's been downhill since the TRS-80
Why dont we just get off the ground...
How strange it is to be anything at all
I'm not sure about American laws, but Sweden makes it mandatory to inspect your car yearly. If not, it is illegal to drive that vehicle. During these checks in special shops, you could easily check the difference between the current driven mile count and the previous one.
Simple and effective.
War is one of the most horrible things a human can be exposed to. And one of the worlds largest industries.

This is called Personal Rapid Transit, and the first PRT system in use was a "demonstration project" in Morgantown, West Virginia, funded by the U.S. Dept of Transportation. (Morgantown is the home of West Virginia University, and the system linked the WVU campus and downtown Morgantown.) It was built in the early 1970s, but I believe it is no longer operating. Subsequent to the development of the Morgantown project a similar system was developed at the Dallas-Ft. Worth airport. All of the "ultramodern" features described for the system in Cardiff were used there: variable destinations, multiple route paths, standby cars to "flex" demand, etc.
The submitter of this article makes a slight mistake in his summary: PRT, including the Cardiff system, does not envision users being able to take vehicles off the tracks. There have been rail- and rubber tire-based PRT systems proposed, but even the rubber tire-based systems are designed for a dedicated, exclusive right of way. (Several mass transit systems, notably Toronto's, use rubber tires instead of rail.)
PRT suffers from a relatively simple problem: massive capital costs. I believe what finally killed the Morgantown project was a moment of clarity at the Urban Mass Transit Administration (UMTA, the U.S. D.O.T. agency that oversaw the project). A consultant pointed out that while the PRT system had been fun, it would have been substantially cheaper to simply buy every student and staff member of WVU a new car every two years. (My stepfather was the smart-aleck consultant.)
The Cardiff project? Three words: Big Government Boondoggle. The fundamental problem of PRT is the fundamental problem of Light Rail and Monorails too: they are dedicated right-of-way solutions that run along an extremely expensive path. (Even if the cost of construction is trivial, the cost of land acquisition is enormous. If the cost of land acquisition is NOT enormous then there isn't sufficient population density to support a fixed right-of-way system.) It is dramatically cheaper to buy buses. It is dramatically more efficient to run buses. Buses can change routes instantly--so buses that "prowl" the city center Monday through Friday can run on suburban loop routes among shopping malls on Saturday and Sunday. And a bus-based transit system only requires a marginal additional cost for right-of-way (bus stop marking, signs, shelters, etc.).
But buses don't have the sex appeal of big transit projects, so people still throw money at thirty-year-old concepts and call them "ultramodern technology."
How 'bout if we haul out the big networking technology of the time, and proclaim ARCNET as "ultramodern" networking?
How do you think Cardiff Arms Park got its name then, boyo?

The biggest reason I see for not doing this is cargo capacity. With a Segway, my cargo capacity is limited to what I can comfortably carry; a backpack or a briefcase.
The ULTra, on the other hand, can carry a dozen grocery bags quite easily, I just need to load and unload them. So I can walk out of the supermarket, load up the ULTra, it drives me home, I unload at my curb or doorstep. Easy.
People are never as simple as their stereotypes. This applies equally to Christians, Muslims, and Emacs-lovers.
You know, SOMEHOW, we managed to get our families around without SUVs for years. The idea that you have to have one for you and your 2.5 children is ridiculous.
But like I said, if you're paying for wear and tear you would have to go above and beyond since roads here are a state by state thing (actually, some are county by county as well). You'd have to track *where* you've been as well, to compensate the correct maintairner of the road.
Also, gasoline is taxed by the state, so you are taxed by how far you drive and how heavy your car is (since weight correlates with fuel economy), but of course people like mr_death conviently forget such things.
#2, he also forgets about the tax on gas; the more you drive and the heavier your auto, the more gas you buy (thus the more tax you pay)....
A true replacement for the car?? It is still a car.. you just have less choice of where you want to go because once you leave your house, you can only ride on the tracks and only go where the tracks lead.. this doesn't seem like a good thing imho..
Finally, someone said it (and is above my threshold) ;)
Normal people don't want their freedom taken away. "Solutions" that restrict us to the narrow routes the planners want us to take are no good.
Public transit is a religion for some though, so we're wasting our breath here ;)
Here in Phoenix, there was an initiative passed called Transit 2000. That link is now dead, but here is one that gives the information about it in more detail. Notice the cost. Notice where it is being put. I live here in Phoenix, and I honestly don't know where they plan on getting space along the roads and freeways they plan this thing to follow - it isn't there. That last site says construction is supposed to begin in 2003. I tend to doubt it. Likely the money will be pocketed by our "illustrious" government.
That is system picked. Want to see what we could have had, for far less money, had our government had more vision, and taken a chance on a proven inventor?
The SkyTran System
This is a system invented by Douglas J. Malewicki, an independent inventor.
Read about SkyTran. I am sure there are a few drawbacks, but I would say the majority of them have been seen to by Mr. Malewicki. His reasoning is sound, and fully documented.
Unfortunately I won't get to see my tax dollars go toward this system...

Dude, if you've been rear-ended five times you must be doing something wrong.
(I'm still trying to figure out what he meant by being "hit" by three different cars but "rear-ended" five times. Is there a way to be rear-ended without being hit? Or does he get hit by the same car more than once?)
I couldn't disagree with you more. "...we need a system that is more affordable and fits in with our lifestyle."
Have you been to a major city EVER? The American dream is to have a big car and drive fast, but it just doesn't scale. That lifestyle has to change. And yes, we do need to kid ourselves with 'space-age transportation pipe dreams', because the longer we wait the harder it will be to integrate those systems with our cities.
You wanna retrofit your car so it plays nicely with other retrofitted cars? Have fun watching people with out of state plates zip by you every chance they get. And have fun convincing Joe-sixpack from BFE that he has to install one on his banged-up Chevy because he drives into town once a month.
St. Petersburg (the real one, not the one in Florida) is built on a *swamp* at the delta of the Neva and has a lovely metro system. The tunnels go down very deep since they go under branches of the river, but they have single escalators that go all the way from street level to platform level (so much easier than London). Of course, some types of ground (e.g. solid rock, permafrost) are less practical to tunnel through.
#4 and 6 = SUV's seem to attract bad drivers.
Long before the term "SUV" existed, I noticed the same about the drivers of Cadillacs and Lincolns. In those days, these were gigantic luxury sedans, and the average driver of them was either about 90 years old, had never bothered to learn how to manuever that land-barge, or just plain didn't give a damn about anyone else. I rather suspect most of them fell into the last category (a*holes), whether or not they were also senile and ignorant...
So what happened? The EPA and mileage standards forced Cadillac and Lincoln to shrink their cars. Sedans are now too small to contain the a*holes' egos, so they buy SUV's, and drive them just as badly as they drove the big sedans. Maybe worse, because these things really are _trucks_ and ought to be driven somewhat differently than a car.
Not that all SUV drivers are like that, by any means. I often drive a 4x4 pickup, which is about the same size as an SUV, but cheaper and a bit more useful for hauling anything but people. (And I do use the 4wd -- I live on a dirt road which was a foot deep in snow this morning, and turns to deep mud in the spring.) I would have bought an SUV instead if I'd realized how soon I was going to have 5 grandchildren -- the Ford Escort "station wagon" really isn't big enough, and neither is the Dodge Dakota king cab. I think I'm a pretty safe driver in my truck, because I don't forget it _is_ a truck, take it easier on the turns, etc., and I'd be equally safe in an SUV.
The a*holes are not a good reason to have the government hammer all SUV owners. The a*holes would still take over the roads in some other sort of oversized ego-haulers. What's needed in the first place is traffic law enforcement. In the second place, drop the CAFE standards, and let the car companies bring back the big sedans for those who want them.
One more suggestion: how about making traffic tickets proportional to the weight of the vehicle? This won't affect good drivers of any size vehicle, but it will get a little expensive for bad drivers in 8500 pound vehicles. And bad drivers are certainly more dangerous to others when they're in bigger vehicles.
The design expressed in "The Roads Must Roll" and
The road system in "If This Goes On..."
The first is a Maintenance Nightmare, the second proposes the smart highway/smart vehicle system in which a driver can allow the system to drive the vehicle or drive the vehicle manually. Any design which imposes a mandatory track and vehicle configuration such as that depicted in the article is a hole into which one can through one's money. Kind of like Samuel Clemens investment in the 18,000+ part typesetter, which subsequently bankrupted him.
Maybe he meant he has been physically hit as a pedestrian 3 times, or had a hit out on him 3 times. Luck him.
In London everyone over 65 gets a bus pass. This means that they are full of blue rinses and proportionally have less crazies on them :-)
Also there are very few school buses, so many kids travel on them rather than being chauffered about in the 3 ton SUVs I walk past every day (stopped in traffic jams - I don't take the bus on that road!)
However at about 4pm there is a lot of crime on bus, since school is out and gangs of kids steal each others' mobile phones. So don't sit upstairs at the back.
PRT's main obstacle is probably ignorance and misunderstanding.
The infrastructure costs for the guideways can be substantially cheaper than say a subway or light rail line. You can run them along sidewalks or media strips so you don't have to buy so much land for one thing.
Plus PRT systems can be built incrementally. You build a loop. Then add another loop. Then add another loop. As the system expands, it becomes far more useful as you create more origins and destinations. Your initial commitment only has to be in the tens of millions of dollars, compared to hundreds of millions for light rail projects. Value for money even compared to road building.
Maximum capacity depends on how many "pods" you squeeze through a given section of track. Taxi 2000 is aiming for half second gaps, which would give you 7000 cars an hour moving along the track. Even if you consider that some will be empty (moving around the network to fill demand elsewhere), that still gives a capacity of 5000-6000 people per hour, one direction. (And if car drivers can be trusted to drive with a two second gap between the car ahead, I don't think half second gaps are out of the question for a fully automatic system).
Here are the main advantages of PRT over conventional bus or train systems:
1) No waiting for a vehicle (except perhaps at peak times)
2) Non-stop trips
Plus the potential is for a system cheap enough that it could operate without public subsidy.
Engineering issues could always mean that the real life system fall shorts of the promise (as it has numerous times in the past), but I think PRT deserves an evaluation in the real world.

SOMEHOW, we managed to get our families around without SUVs for years. Cars used to be bigger, especially on the inside. The CAFE mileage limits shrunk the outside. The safety standards require thicker sides, and thicker padding on everything. All the pollution stuff in the engine compartment plus the crush zones require more length in the hood. Result: much less room for the passengers. The backseat of a new Buick gives hardly more room than the backseat of a 1968 VW Beatle, and the bug was a sub-compact!
The other thing, of course, is that the baby boomers are getting older. That means wider waists, back problems, bigger rears, arthritic knees, and more fat everywhere. (This of course doesn't apply to me. 8-) I might be 48 and 55 pounds heavier than I was at 20, but I'm just well-padded, and that knee has been bad since high school. It just hurts more when I try to fold my legs into a little car, lately. Cars must be getting smaller...)
"since taking one means you won't have access to your car it probably will never take off"
This is faulty logic. Taking one means that, for a large amount of transportation needs, you don't *NEED* access to a car. Remember, PRT provides is point-to-point, no waiting, direct transportation. That makes makes it an exact replacement for intra-city car use.
PRT (Personal Rapid Transit) systems like this one are demand driven, meaning that when you show up at the station, you take the first available car. During peak times you may have to wait a minute or two, but during off-peak times there will be one right there.
So you can have what you want, when you want, for how much you want it (unless a measly $1-2 is too much for you)
Everything's been downhill since the TRS-80

I can think of several reasons:
* weather,
* safety - it can be quite dangerous to ride a bike in cycle-unfriendly traffic, particularly in the busy part of town, and most cities don't have much in the way of cycle paths.
* disability (and I don't mean lack of fitness - cycling is a great way to build fitness).
I don't use a bicycle much for the second reason (amoung other reasons, I have to cycle through a dangerous intersection to get anywhere), but cycling is an excellent mode of transport where possible.
I consider myself lucky that I live within easy walking distance of work - my second favorite form of transport.
Please actually back up your claims as to SUVs being so much more dangerous and causing more accidents. I see many more smaller passenger car accidents than SUVs.
SUVs account for 100% of all accidents that have occurred to my toyota. given that 1 isn't a great sample size the fact that my car was parked at the time and the person was on the phone eating a burger didn't make me happy either
--- As to make my comment seem, by comparison, more intelegent... doodie doodie doodie poop poop poop!
And back then you could pack all the kids you wanted in the back seat and you didn't even need a safety belt much less a full child safety seat. By the way, in case you haven't installed one recently, most child safety seats take up more room than a seriously obese adult.
In most states the use of such seats is mandated by some very stiff laws. And it's not unusual to need two such seats in a car. There goes your whole back seat. You can't even fit a child between the two safety seats in most sedans I've seen. Even if you did, I have serious doubts about the safety of that child in the event of a side collision.
Maybe you've seen something I haven't. I have two young children ages 22 months and 3 years old. We have a large station wagon. It's a squeeze getting a third person of any size in our back seat. And I still worry about the crashworthiness.
Now you know the reason why people drive these behemouth road monsters. Once you install two child carrier seats, there really isn't much choice. When my family can fit in to something smaller, believe me, I won't hesitate.
Nearly fifty percent of all graduates come from the bottom half of the class!
You are right - it isn't a new concept. Quite interesting though!
To see an example of a somewhat similar system try this link to the RUF system
'Round here folks mostly live in the suburbs and spend much time in their cars. To get from your home to work involves equal parts side streets, highway, and city streets. People are too spread out for trams and buses (You may have noticed rail doesn't work here either).
---If you can't trust a nerd, who can you trust?
Its a free country folks...
The country may be free, but the roads are not. Nor should they be. There is already extensive regulation for the roads and the vehicles that ride on them. The US at least is (at least by reputation) a representative democracy; if the people decide to regulate SUVs harshly, so be it. Civil liberties are not at stake. The constitution does not grant people the right to drive at all, much less to drive whatever they want however they want.
Lets lower the crash energy of every vehicle while we're at it. Lets lower the speed limit to 5 MPH...
You're right, that's silly, let's all drive souped-up Kenworth semi-tractors at 180MPH everywhere we go, that would be much more reasonable. Reductio ad absurdum cuts both ways.
So, you're willing to give up your privacy to allow the gov't to track everywhere you've traveled? Remember, if we're compensating for the wear and tear on a road they're going to need more than simply milage.
Few taxes work that way. Property taxes to support schools are not dependent on how many school-age children the taxpayer actually has, for example, and taxes paid to support the local police force aren't graded depending on the quality of the taxpayer's neighborhood. And for that matter, we already pay taxes to support the roads, without supplying any information at all about where we go when we drive.
A real-world tax like this would be based on mileage, the proceeds divided among the local road-maintaining agencies according to some precalculated formula. It would not be perfectly accurate. Taxes like these are not.
The second they find statistical evidence that SUVs (and SUVs alone, they control for the usual supsects: age, gender, marital status, past history, etc...) are causing them to lose more money (due to claims) than any other vehicle you can bet your bottom dollar that rates on SUVs are going to rise (if they haven't already).
Your argument sounds good at first, but it's weakness is actually something you touch on. Insurance rates don't correspond with hazards, but with *claims*, and claims and hazards may not always be perfectly proportional.
Studies have found that in fatal collisions between SUVs and ordinary cars, the people in the car are about 30 times more likely to die than the people in the SUV. A person who dies instantly does so quite cheaply, whereas a crippling injury or a long, lingering death in the hospital is more expensive.
Additionally, dead people make pretty poor courtroom witnesses - it may be a lot harder to show that an accident is the other driver's fault (thus using his insurance to cover the costs) if you're dead.
Combine these factors with the fact that the SUV passengers are likely to be unhurt, even if the passengers in the car have been killed, and you have a formula for actually lowering the insurance rates for SUVs, even though they are a greater hazard to other vehicles on the road. This is exactly what has happened.
In any case, I don't think it's quite as simple as (more_dangerous) == (more_expensive). Once you pass a certain danger point, the cost isn't money anymore, but human lives.
Subway -> Supertram
Tokenring -> Ethernet
I wonder if they have the same collision algorithm.

Yes, I know that for the typical cost of a mass transit system, you could have bought every regular rider at least one new luxury car. But:
1) How was the cost of building the roads factored in? Not fair to compare the cost of a new railbed to just stuffing more traffic into existing roads... I'm not sure about this, but it would seem like a mile of dual-track railbed built only heavy enough for car-like vehicles should cost less than a mile of four-lane road, and (with central control) would handle more traffic.
2) I'd think the cars for one of these systems would actually be a little simpler than an automobile built for independent operation. Electric motor instead of that horribly complex gasoline engine and transmission. Simpler suspension, because you can count on the rails meeting certain standards for smoothness, and no steering. Lots of electronics, but that's cheap nowadays. So if the cars were built in sufficient quantity, they'd cost the same or less as autos.
Of course, the trouble is that autos are built by the millions, but trams are custom-built. Could you design the trams to use an existing car body, just drop an electric motor under the hood, leave out the steering, and change the wheels?
A real-world tax like this would be based on mileage, the proceeds divided among the local road-maintaining agencies according to some precalculated formula. It would not be perfectly accurate. Taxes like these are not.
I know, maybe we should put a tax on gasoline. You know, the heavier the auto and the farther you drive the more taxes you pay. Wow, why didn't anyone think of tha.... oh, never mind.. they have.
A person who dies instantly does so quite cheaply, whereas a crippling injury or a long, lingering death in the hospital is more expensive.
But you still may be liable, therefor have to dish out a lot of cash (or your insurance company does). Back to the arguement though, statistics show that single males under the age of 25 cause more accidents as well. Should we tax them above and beyond the norm? What about folks who live in citys and suburbs where accidents happen at a higher rate than those out in the country? Do we tax them as well? If you want to tax in order to promote safty why go *only* after SUVs?
Additionally, dead people make pretty poor courtroom witnesses - it may be a lot harder to show that an accident is the other driver's fault
Or you could say that juries are going to be moved that someone IS dead. If an accident happens and death is involved you can be damn sure its going to get more attention than your average fender bender. I think the police/court will have more information on hand than simply witness testimony.
Studies have found that in fatal collisions between SUVs and ordinary cars, the people in the car are about 30 times more likely to die than the people in the SUV [suv.org].
Wow.. if I read somewhere that I'd be thirty times more likely to die in a motorcycle accident if I didn't wear a helmet I would think that's a damn good reason to wear one, wouldn't you think... Of course that's not the point your trying to make, but that may be because your arguement is bunk. You haven't shown that SUVs are the cause of more accidents, just that if your in one you're more likely to survive. Now, had you shown that SUVs cause more accidents you *might* have something.
And just in case anyone's wondering I drive a compact car. I think SUVs are a waste of money... but I think a lot of things are as well, I just don't try to change laws to keep other people from (IMO) wasting theirs.
Why to you is it?
Woah.. Why to me is lugging myself around in an SUV so unappealing? For the reasons you've mentioned. I completely agree with your reasoning. SUVs are crap. Even misnamed.. Think SAV. Suburban Assult Vehicles. That's what they really are.
Furthermore, I feel like I should be able to claim damages against SUV hogs^H^H^H^Hdrivers for ruining my planet, and putting me at risk.
Why do people want SAVs? Because the car corporations tell them to. Americans almost always do what corporations want them to..

The US, unlike all of europe, is and has always been big and spread out. This is why air travel is in chronic overdemand, and rail travel can't make a profit anywhere outside the northeast corridor. The same is true of cities. If people are traveling from urban to urban locations, they don't need cars. But hardly anyone outside of the biggest and oldest of cities is doing that in America. I'd guess 99% of the trips in this country are made to and/or from rural or suburban areas. This is partly the result of the ascendance of the car in America, and partly the cause of it.

Better not to move people at all if not necessary.
I personally think that SUV's are an obvious danger to drivers of ligher vehicles. More to the point, all heavier vehicles are inherently more dangerous to others than lighter vehicles in exactly the same circumstances (baring special cases, e.g., matching bumper heights).
However, the SUV is clearly a facile way to avoid the limitations placed on cars. It is probably illegal, but IANAL. SUVs are clearly used for personal transportation, so they are cars, not trucks. They are used less like a truck than a station wagon is, because it's more difficult. My wife prefers a subcompact station wagon to an SUV because it's easier to haul a harpsichord around in one. Cabinets also. In an SUV one would need to take out the back seat. In a station wagon, you just fold it down. I will grant that the absolute limit on the size of what you can haul is larger for an SUV, but because of convenience, it isn't used as a truck, whereas station wagons frequently are used as trucks. For an SUV to be classed as a truck and a station wagon to not be so classed is an aovious perversion of the law. I suspect it of being actually illegal, but nobody who has standing to sue over the enforcement is likely to bother.
The entire category of vehicle would never have been created if some scoundrel hadn't decided that this was a good enough loophole to pass through. And I suspect that what he noticed was that only the government had standing to object, so that with a friendly legislature in place (expensive, but they'd already been doing it for other reasons) nobody would challenge them.
I don't really care what you claim to drive. It's quite irrelevant. I don't drive at all. So? Physics, Economics, and Politics don't change because of that. Your denials require a lot more evidence that the prior assertions, because what he is asserting is what one would expect from the known characteristics of the situation and basic models of how massive bodies move in space-time. It's the denial of those predictions that requires a lot of examination and explanation. Of which you provided none. Merely challenging the claim of certain effects which are what one would predict from even a crude modeling of the situation. (And I will grant that my model is quite crude. I didn't put any numbers in at all. I basically modeled it with swinging pendulums with differing plumb weights, and towers of blocks.)

I think we've pushed this "anyone can grow up to be president" thing too far.
In the mid 1970s I noticed that the worst drivers tended to come in two clumps. For brevity I identified them as the Cadillacs and the Volkswagens. They didn't actually all drive those particular brands, but one mode drove big heavy expensive cars, and tended to project "Get out of my way. I'm not even going to notice you." and the other mode drove small agile cheap cars and tended to project "I can dodge around anything!".
Both were lousy drivers.

I think we've pushed this "anyone can grow up to be president" thing too far.
If your in a small car and your going to hit the side of a sports utility car (SUC), aim for the wheels since thats the only impatct area where the a smaller car's crush zones work. It will also transfer more energy into the larger vehicle with a result of turning 30:1 car/truck death rate around. Your very likly to flip the truck which will likly kill its occupents but had they chosen a car closer to the average mass on the road, everyone would have walked away.
But here it is. Yes, San Francisco Muni just retired the last Boeing streetcars, which were amazingly unreliable. But they're not all dead yet! Manchester, England is buying a few to tide their system over until they can get some new cars.

Vandalism is already a problem on buses. And there one has a driver available who is expected to prevent it. These things are small enough that a group of 1-4 kids could reasonably expect to be alone in it. Vandalism would not be observed except by a selected group of witnesses. One might expect that in such circumstances that vandalism would quickly become intolerably bad.
The primary deterent to vandalism currently is ownership. But in public transit the ownership is so dispersed that it becomes an ineffective deterrent. Other approaches to deterrence that have been found have inherrent problems. (Video cameras are easily spray painted, e.g., and are relatively ineffective as a deterrent anyway, unless there is someone close at hand monitoring them.)
.
I think we've pushed this "anyone can grow up to be president" thing too far.
Let me document them:
I have been hit as a bicyclist once, pedestrian twice. Once while in a cross walk because the driver wasn't paying attention and once a car came out of a driveway and again wasn't paying attention. Both times, I was talking to someone who was at the opposite direction and was looking at them.
As for car-car accidents, first time I was at a stop sign, and got rear-ended by a lady screaming at her kids. Second time, someone let their car roll forward in neutral (that didn't do anything other than a scratch), Third time was someone not paying attention reading a movie theater sign and not looking at the traffic. Fourth time was in a campus parking lot and my car was hit after it was parked (go figure). Fifth time, the guy was on a cell phone and I was stopped in traffic for quite sometime on a freeway and promptly got smashed into (he was going around 55).
I just have bad luck with cars.
Dacels Jewelers can't be trusted.
SUVs account for 0% of the accidents that have happened to my poor cars. (5 accidents, as stated above).
I think that the major problem isn't that it's SUVs, it's that people do too many things while driving. I'm totally for banning cell phones without handsfree devices (still not that good, but sometimes you actually have a necessity to talk). Stupid people are everywhere, SUVs only in some places. I'd rather ban (or tax) stupidity.
Dacels Jewelers can't be trusted.
The "VWs" were kids -- who tend to think they have infinite reaction speed, and their luck will never give out. Yes, they're dangerous, but if they survive they'll learn better. They might be more dangerous now, since they're more likely to be driving small agile 4x4s instead of 2,000 pound foreign cars.
OTOH, the "cadillacs" will never learn...
After I bought my car, I got rear-ended on my birthday for the next three years... How's that for bad luck... Ok, the third time wasn't my birthday, because I decided to stay home that year, but got rear-ended on Thanksgiving holiday, which is close enough....
,and then POW.
1.) I was at stop sign, and lady behind me didn't care....
2.) I was at Taco-Bell drive thru, and lady behind me was looking for change.....
3.) I was on freeway, and guy behind me just wasn't paying attention.... Traffic stopped... I was stopped for a good 3 seconds
So, you're another person who thinks that everyone else ought to conform to your ideas.
So are you, apparently. That's ok, most people are like that.
I don't suppose you've ever tried to put a family in your car have you?
Try a minivan or a station wagon. Manufacturer seem to want to go more towards sedans, but those things are nasty and cramped.
Minivans are big like SUVs, but with less evil. Sometimes it seems that SUVs don't have low beams...

In high school I t-boned a guy who ran a red-light.
In college, I was a bike rider, walking my bike across an intersection, and a lady making a right turn, thought she could just blow right by me without even looking, even though she had a red... She nailed my bike, and I wound up on her hood.... She got pissed at me, and got out and yelled at me... LAPD happen to be at the intersection, and saw the whole thing....
I personally think that SUV's are an obvious danger to drivers of ligher vehicles. More to the point, all heavier vehicles are inherently more dangerous to others than lighter vehicles in exactly the same circumstances (baring special cases, e.g., matching bumper heights).
First, "you personally think" which is one of the points I've been saying. What someone personally thinks is fine for the way they conduct their lives, but does not necc. good policy make. As I said before there's tonnes of stuff that I personally think, but that dosesn't mean they should be made law.
As for SUVs being dangerous simply because they're bigger than lighter cars, the same can be said about midsized cars and compact cars, or compact cars vs. cyclists, or cyclists and pedestrians, or tractor-trailers vs anything else on the road that moves... so why the fuss about SUVs only?
The entire category of vehicle would never have been created if some scoundrel hadn't decided that this was a good enough loophole to pass through.
Speculation. You could argue (and I would agree) that they would probably have been more expensive since they would have had to conform to stricter guidelines, but that doesn't mean they wouldn't have sold. Last time I checked SUVs were pretty expensive to beging with. People seem to have no problem dropping a big wad on 'em.
Your denials require a lot more evidence that the prior assertions, because what he is asserting is what one would expect from the known characteristics of the situation and basic models of how massive bodies move in space-time.
Wow.. at what point did I ever argue against gravity/physics... uh yeah, never. I never said that SUVs that have more mass didn't crash with more force. What I did argue was that the that was given was to statistics that show that people in SUVs survive crashes at a higher rate than those in smaller cars. That *is not* the same thing as saying SUVs cause more accidents (which is what the poster was implying.. maybe if you weren't playing with pendulums and plumb weights and actually used some logic you might have noticed that). No statistics were shown that a) controling for external factors SUVs cause more accidents than non SUVs or that b) controling for external factors accidents involving one SUV and non SUVs result in a higher death rate. Do such statistics exist? The previous poster surly didn't provide them (funny how he's not held to the same standard of evidence as I). I have a hunch that there isn't for a) and some for b)... lets assume that b) is true and go back to my previous arguement. I would also then think that a crash involving a Lincon Town Car and a Fiat would result in the person in the Fiat dying more often than two Fiats crashing (or two Town cars crashing). Or an accident with a Fiat and a cyclist. If everyone's so hell bent about size/saftey why the witchhunt after SUVs and not *all* autos?
Why not?
It's either take 45 minutes to an hour to drive to work, or take 2.5 hours taking public transportation... Seriously... Bus to transit center, takes like 45 minutes. Then I get to wait for the stupid train. Since its light rail, the train takes 90+ minutes to travel 20 miles. And this light rail is so awesome... NOT... They recently expanded it, built a shiny stop in front of an abandoned building. And put the rest of the stops in places nobody needs to go to.
Depends on where you are. Here in San Francisco over 2/3 of residents use bus or light rail on a regular basis, so there is very strong support for public transit despite persistent reliability problems.

I know, maybe we should put a tax on gasoline. You know, the heavier the auto and the farther you drive the more taxes you pay. Wow, why didn't anyone think of tha.... oh, never mind.. they have.
What is your point? I was pointing out that we already have a system of using taxes to support roads, and no information about where we travel is gathered. This is that system. What are you arguing with, exactly?
statistics show that single males under the age of 25 cause more accidents as well. Should we tax them above and beyond the norm...
I was talking about insurance, not taxes, and I thought it was pretty clear. Insurance is graded by a person's demographic, and young single males are charged more than others for insurance. Are you arguing that this is unfair?
Contrary to your post, I haven't advocated a tax on SUVs. I was merely pointing out that a tax that required extensive data-gathering of the sort you suggest would be an exception to the way taxes usually work. An extra, mileage-based tax on SUVs is more feasable and less problematic than you suggest.
If an accident happens and death is involved you can be damn sure its going to get more attention than your average fender bender. I think the police/court will have more information on hand than simply witness testimony.
What information could the police possibly have other than witness testimony?
Perhaps you mean the police would try to obtain testimony from witnesses who were not actually involved in the accident. It would certainly be commendable for the police to do so. Did you know that fatal accidents are actually disproportionately rual, not urban? More accidents happen in urban areas, but the speeds are lower and they tend to be less serious. Many serious traffic accidents have no non-involved witnesses.
You haven't shown that SUVs are the cause of more accidents, just that if your in one you're more likely to survive. Now, had you shown that SUVs cause more accidents you *might* have something.
Actually, I'm showing that if you're driving an SUV, you're more likely to survive an accident - because the other vehicle most likely will suffer much more than yours. I'm not even trying to show that SUVs cause more accidents. SUVs don't have to cause more accidents than cars to pose a hazard. If the accidents involving SUVs are more deadly, you'll end up with more total deaths even if the number of accidents stays the same. This may actually be happening; traffic deaths have recently started to rise for the first time in decades.
In another message you posted on this same subject, you actually admit that:
I never said that SUVs that have more mass didn't crash with more force.
I have a hunch that there [is evidence for] accidents involving one SUV and non SUVs result in a higher death rate.
lets assume that [accidents involving one SUV and non SUVs result in a higher death rate] is true...
Who's side are you on here, anyway? At least in that post you said something that made some sense:
I would also then think that a crash involving a Lincon Town Car and a Fiat would result in the person in the Fiat dying more often than two Fiats crashing (or two Town cars crashing). Or an accident with a Fiat and a cyclist. If everyone's so hell bent about size/saftey why the witchhunt after SUVs and not *all* autos?
Yes, in a small car/large car collision, the small care fares worse. But there are numbers for this stuff. SUVs, largely because of the high bumpers, are much worse than even the largest large cars. A quote from the safety page at suv.org:
The NHTSA study concludes that 2,000 people would have survived if their vehicles had been hit by a heavy car instead of a heavy SUV. Two thousand is five percent of the nation's annual traffic fatalities. The study declares that light trucks and SUVs are twice as likely to cause a fatality in the struck car than a passenger car of comparable weight.
As for why the "witchhunt" focuses on SUVs in particular, well, do the math. What car is even remotely in the same class as these behemoths? What car weighs as much as a Chevy Suburban or Ford Excursion? There is no such beast. According to the study mentioned above, a Chevy Suburban is probably about *twice* as dangerous as a car *of the same mass* - and there are no such cars. The very biggest cars only weigh about half of what these monsters weigh. These giant vehicles aren't just slightly more dangerous than passenger cars - they're a lot more dangerous.
Sometimes, when people get alarmed, it's because something alarming is happening. It's not always a "witchhunt" or hysteria.
if you can't see what this is about,you are truly out of touch. C`mon people wake up! every single aspect of your life is gonna be controlled!!! your just going to be hearded like cattle taking you back and forth to your factory(work) monitored by cameras so everyone does what thier told to do and goes where "they" send you to. this isn`t FREEDOM it`s a SIM CITY of mindless drones. you geeks are so smart your stupid, stop looking at everthing in the here and now. if you don`t take a hard look at what`s coming down the road your not gonna see it coming until you wake up one morning and wonder what happened......
I remember seeing a similar story on Beyond 2000 (Australian series) circa 1994... it involved a 'packet model' transport system where there was a main shared carriageway (for high speed traffic) and off-shoot branches to service the stations. I can't remember much more info than that, but they had a test track and everything as well, so this is definitely not a new idea or first implementation (so no patents for them!).
What is your point? I was pointing out that we already have a system of using taxes to support roads, and no information about where we travel is gathered. This is that system. What are you arguing with, exactly?
The earlier post by Mr_Death (that started this whole thread) had advocated a tax on SUVs (or all cars) on weight/use. I assumed (apparently incorrectly) you were advocating the same thing. I was pointing out that such a system already exist.
I was talking about insurance, not taxes, and I thought it was pretty clear.
The orig. post (by mr_death) *was* about taxes, or at least making SUV owners pay money into an SUV fund. My point was that *if* you're going to make SUV owners pay extra into an SUV wreck fund because they cause more accidents then you better do it for guys under 25 because they cause a disporportionat amount of accidents as well.
Then I pointed out that this is *exactly* what insurance companies do anyway.
Insurance is graded by a person's demographic, and young single males are charged more than others for insurance. Are you arguing that this is unfair?
Not at all.. see above.
[about accident data] What information could the police possibly have other than witness testimony?
Um, skid marks, ammount of damage to car, where the accident actually took place / position the cars were in after accident, were tail lights actually working (things you can actually determine after they've been smashed all to hell), was anyone drunk/high... there's LOTS of forensic evidence you can use to recreate an accident. Yes, all eye witnesses *would* be prefered, but you can still paint a pretty damn good picture of what happened without one. And, as I said in the last post, *if* there's death involved then the police are going to put a hell of a lot more effort into determining exactly what went on than if there's a simple fender bender. Possible negligent manslaughter tends to attract more attention. The assumption that just because one of the parties is dead in an accident the police are just going only listen to the surviving driver's statement and fluff of the investigation is laughable.
Contrary to your post, I haven't advocated a tax on SUVs. I was merely pointing out that a tax that required extensive data-gathering of the sort you suggest would be an exception to the way taxes usually work. An extra, mileage-based tax on SUVs is more feasable and less problematic than you suggest.
Which, again, was my point. A system of taxation already existed, but the poster was advocating more taxation (either because he forgot that gas was already taxed or just feels like taxing the crap out of anyone who drives). If taxing gas wasn't enough to cover the wear and tear as he implied my point was what other way do you determine such things?
Actually, I'm showing that if you're driving an SUV, you're more likely to survive an accident
The stats you orig. posted say this...
- because the other vehicle most likely will suffer much more than yours.
but not this... at least not in that post. You said that " the people in the car are about 30 times more likely to die than the people in the SUV"
If the accidents involving SUVs are more deadly, you'll end up with more total deaths even if the number of accidents stays the same. This may actually be happening; traffic deaths have recently started to rise for the first time in decades.
Again, that's exactly was I said in the parent post! To say that SUVs are more dangerous you have to a) show that SUVs are in more accidents (external factors notwithstanding) or b) an accident involving an SUV and a smaller car causes a disproportionately large amount of injuries. The statement 'someone in an SUV is 30 times as likely to survive an accident' proves neither. Now, you do finally point out that one study concluded that 2000 deaths would be attributed to SUVs and SUVs only, which leads me to....
Who's side are you on here, anyway? At least in that post you said something that made some sense:
I was trying to make a point that even if b) is true I still don't think its a reason to villify/tax/ban SUVs. Lets get rid of all SUVs and then look at accident rates. All of the sudden the next largest vehicle is going to be the bad machine on the block with damming statistic about how when they plow into smaller cars a disproportionate amount of deaths happen. So ban them as well, then the next largest becomes the statistical killer... and so on and so on.. and the next thing you know we're all driving Fiat Cinqucentos.
And why isn't there a big push to get sub compact cars off the road? An SUV, a large car, hell even a midsize/economy car is likely to mangle you if you crash in a VW rabbit or a Geo. Isn't it just as irresponsable to drive around in a tin can of a car than it is to drive around in a big ass tank of a car?

One problem with Slashdotters is they don't know a lot about a lot of things... Like the French worked on such a thing from 1969 up to 1987! Bruno Latour, a French sociologist of technology, wrote about it in a book called "Aramis." You can read about it at Amazon. The reviews even say it was like packet switching. Unfortunately the reviewer doesn't understand the book, and says incorrectly that the project was "squashed by the French government." I had to read it for my doctoral exams... This is an idea that doesn't work, but since so few people know about technological failures and the basics seems easy enough, it keeps coming back. It's framed as "no one has done it, it must be cool!" instead of "no one that I know of has succeeded with this, perhaps they've all failed!" It is not the first of its kind at all, the author of the article has no idea what he's talking about.
Take a bunch of those flat escalators they have in long airport terminals, speed them up by 5-or-so times, plop them down all over the city, and suddenly being a pedestrian isn't BORING anymore! It's like an amusement park ride every time you try to go somewhere! Just make sure you have good life insurance. ^_^
[insert witty comment here]
You don't drive your SUV down the supermarket aisles, do you? And yet somehow even 70-year-old grandmothers manage to move their groceries to the checkout stand. I think you need to reassess your assumptions.
Quoted from article:
A true replacement for the car!No. When the vehicle is mine personally, and I can leave my crap kicking around on the front seat, and most importantly that it goes where I point the steering wheel, then I'll call it a car.
Public transit proponents apparently don't understand the visceral pleasure of punching the gas pedal and peeling the rear wheels. Much like I don't understand the pleasure of hugging a tree.
The first is a Maintenance Nightmare, the second proposes the smart highway/smart vehicle system in which a driver can allow the system to drive the vehicle or drive the vehicle manually. Any design which imposes a mandatory track and vehicle configuration such as that depicted in the article is a hole into which one can through one's money.I should think those would be the least of their worries. If the car isn't my own vehicle and I'm given sovereignty over it, there'd better be a rental company paperwork nightmare every time I get into a vehicle by myself.
Otherwise, I would think that going to work in a car where the seats were still full of the back-from-the-pub puke of the previous patron would be the *least* of Cardiff's worries.
How do *you* treat a car that you don't care about? Spilled ice cream? Overloading it by carrying 20 sheets of drywall? Kicking doors open?How are you going to track down who did the damage to a vehicle which appears to function autonomously?
Quoted from BBC's article:
vandal-proofThat sounds like a challenge. But, to paraphrase an old saying, invent a vandal-proof device, and someone invents a better vandal.
This is just another reason for anyone who can afford to leave a place which imposes high taxes and affords no standard of living to do so: if this is forced on the city, they can expect an exodus of doctors, scientists and engineers.
Most disturbingly, those who would normally espouse public transit at all costs are also usually the most staunch advocates of privacy rights. And yet, there appears to be no great outcry from the fact that your access card would, by necessity, have to track your every movement for fare calculations, and your ID for damage control. Don't want the government to know that you go to a gay bar every Tuesday night? Or that you're a closet white supremacist? Or even what supermarkets you shop at? Tough. They'll know.
This is sheer idiocy. I was born in Cardiff. This and Tom Jones are both good reasons not to go back.

Or you need to suck it up and move closer to work.
Damn...I'm sure I saw this years ago in that Woody Allen film The Sleeper....

You're exactly right on the private ride and security features, although I'm not sure if ULTra has a panic button. There's an additional deterrent: Only the person buying the ticket knows the destination ahead of time. If you were a mugger or rapist, would you force your way onto a monitored Taxi2000 car without knowing where you were going, and the only control you have is to hit the Panic Button, which only means alerting the police? Of course you wouldn't.
However, insurance doesn't address the less tangible detractions of cars in general, and SUVs in particular: the fact that, as a benign pedestrian or biker, you have to spend lots of mental energy to keep yourself from getting killed. While you don't endanger anyone else, you are at constant threat by people who are not significantly endangering themselves. It's asymmetric, backwards, and very frustrating.
At least motorcyclists are endangering themselves more than the world around them, which some people consider stupid and destructive, but a more socially-minded person would see as good, because there is little virtue in protecting yourself, but much more virtue in protecting those around you.
it was called the trolley, you could go coast to coast changing from one to the next practically, all major cities had them. the auto industry bought the trolley lines, closed them down, the government helped to promote the highway system after heavy lobbying from the auto industry, it would cost trillions now to replace what we already had
I live in Brisbane, Australia where a Electric Tramway system was in existance for the first two-thirds of the 20th Century. This system had started out with a much smaller network prior to 1900, horse-drawn initially.
...he travelled by limo, and trams passing close to his home may have been a Sound annoyance to him.
It was expanded to be quite a substancial system.
The Lord Mayor of Brisbane during the Sixties never liked the trams
So he engaged an american Traffic Planner, with the result that our fine Tramway System that had grown through the years was scrapped, and replaced (in part) by a Southern, and City Internal East-West, Elevated Freeway System!!!

Melbourne wasn't so stupid -- they've still got their trams!
