Researchers Apply P2P Principles To Car Traffic
alphadogg writes to tell us that lessons learned from peer-to-peer networks are being applied to traffic systems in order to prevent jams. "Their Autonet plan would center around ad hoc networks of vehicles and roadside monitoring posts supported by 802.11 technology (the prototype uses 11b). The vehicles would essentially be the 'clients' in such a system and feature graphical user interfaces to pass along information to drivers. They're building the system to be able to handle data on thousands of traffic incidents and road conditions."
This technology may help people avoid problems once they occur, but it won't do squat to affect the root of many problems -- bad traffic planning. Without a good traffic plan, everything made to "fix" it is just a patch on top of a bad base.
Words "network collision" are going to take a whole new meaning :)
cool.
Put the damn money into comprehensive public transportation!!
... that senior citizens cause bottlenecks on the internet just like in cars! :-)
Lord knows my grandma on the internet is a disaster.
We figured out a long time ago that it's easier to elect seven judges than to elect 132 legislators.
research on this sort of thing has been going on for almost two decades now. the increasing ubiquity of in-car nav systems, cellphones with gps, and other positioning and communications technologies helps to overcome the biggest hurdle: critical mass. this sort of system isn't useful if only a handful of cars have it.
the other, and more difficult, part of this work is using this data in a way that can provide predictive travel information to drivers before that data becomes outdated. it's one thing to know about congestion on a road 10 minutes from your current location. it's better to know whether it's still going to be congested when you get there. models to do this sort of thing exist, but aren't (yet) fast or reliable enough to be used in real time.
in urban areas, there's been an increasing push for taxis to be outfitted with gps transponders both as a political move, but also as a research tool and eventual mechanism for supporting real-time traffic data collection. taxis in major cities cover all the big and little streets, all over the place, all the time. they're perfect for fitting into a regional live traffic data collection system.
Not really. Phenylpropanolamine causes hemorrhagic stroke -- aka bleeding in the brain. That's why it's "hard to come by these days."

Maybe it's just me, but my trust in meth instructions is inversely related to the number of spelling errors.

These aren't the 'roids you're looking for.
The increasing tendency to use this type of communication to support critical infrastructure is an open invitation to chaos and disaster induced by malicious hacking.
Consider for a moment all the past reports of external hacking on U.S. infrastructure and the chaos they created. Now imagine what would happen were this to be hacked after widespread adoption.
You all very well know that from the moment of its inception there will be concerted efforts to do just that.
No thanks.
Leave out the networking with private vehicles and it gets a bit better, but there's still a vulnerability.
Again, no thanks. It can't be made hacker-proof.

...old people lag bad! Someone needs to upgrade them or scan them for spyware or something hehehe.

Automation is one thing, driver education is another.
Defensive driver courses are a much better target for the money, as they benefit the people driving directly. Even teenagers can take them. Plus, you get 10% off of your car insurance. AAA handles them all over the place.

So I take it that trust doesn't extend to tech news stories? Remember what site you're on, man.

I'm the opposite when it comes to trusting authenticity. Remember how often meth labs blow up...
93rd rule of Slashdot: No matter how obvious my sarcasm is, my comment will be taken seriously by someone.
A lot of the unnecessary traffic delays at poorly regulated traffic lights could be completely circumvented by getting rid of lights and settings up roundabouts. Even through traffic slows down, it does not stop, and it automatically regulates itself.
Roundabout takes very little time to get used to, and it presents a consistent interface to drivers. First time I saw them in Italy many years ago during a business trip, I instantly fell in love with them. Since then I've seen them all over Europe. I think most drivers in my area (Silicon Valley) would love them, too, as everyone seems to be rather impatient (which is quite understandable with the unending traffic jams and poor timing of traffic lights contributing to the jams).

Not having RTFA, I think that the biggest problem is, unless all you're doing is adding entrance ramp traffic lights, is the drivers. If they have to obey some sort of changing speed limit sign or something just as "voluntary," they're going to ignore it. Where I commute, as soon as people get on the highway, they stomp on it even though they know that in a mile and a half they're going to be going 5 mph.
But at least they'll be ahead of that Prius back there. Dang liberals!

Is this thing on? Hello?
For several years now I've wondered if traffic planners ever talk to physicists, specifically with regard to fluid dynamics. As a non-physicist, natch -- though I did date a nice lady once who was a traffic planner in a large city -- it seems to me that this could produce some good ideas, perhaps a traffic version of PARC. Internet researchers are equally, if not more, qualified to pipe up here and I'm interested to see what they come up with.

Cars cannot use P2P technology because the principle of driving a private automobile is exlusion and luxury. If you start sharing (P2P) then you get the bus or a train - you start getting intelligence - the economy would collapse if we started not requiring a 2 tonne cage to move a 150lb load.
Stupidity is its own reward.
Isn't that the communications network for the Autobots? This whole traffic management plan is a Decepticon plot I tell you! It must be destroyed!
Cars give us a tremendous blindness to the necessity of collective action. We are all just atoms driving cars and the problem is the Others who are Traffic and get in My way.
You are correct in pointing out that the biggest subsidy from those who don't drive to those that do is the Grid - the road network (I always think it is funny how people move out to the Country to get Back to the Land and buy and SUV to do it) but manufacturing systems are heavily subsidised as well (ecologically)
But how could we get around if we didn't have public roads? We can't without some public access. Right now that public access is dominated by private cars and you can't even walk in front of your own house with out threat of getting killed and run over.
Hitler loved the idea of private cars that is why he funded the first comprehensive car network - the Autobahn. He imagined a race of Atomic Supermen! Super individuals. We have become that.
We can't even see how impossible it would be to drive without all this car subsidy/network and how that network excludes all others.
I agree with you on one individual right: We should all be able to walk around safely in public. That means we need to ban cars.
Stupidity is its own reward.
I'm surprised that nobody has mentioned this yet (and that this story isn't tagged 'privacy'):
Isn't anyone concerned with the fact that this kind of system would easily allow anyone to know where you are (assuming you are driving or have driven recently) at any time?
Talk about a social engineer's paradise.
I like to think that I am pretty objective, and you have presented one side of the argument. I agree with you and I'd like less noise, danger (when walking just around the block) and pollution, but cars are *extremely convenient.*
Anywhere outside of the dense city, it is the quickest, cheapest (on a marginal cost in most cases, anyway) way to get anyplace. All major cities that I've lived in have smelly, gross transportation systems (Boston, NYC) as opposed to a nice, comfortable, climate-controlled vehicle.
Americans love their cars because of the convenience -- it facilitates laziness and comfort. The only way to change this is to make it more un-economical to use, or improve the alternative (public transport.) In a way, I'd like to see both, but I do like having a car after taking the bus in all of my student years.

I took the bus during my student years as well. The bus was the same speed, or slightly slower than, walking. If you were an hours' walk away from where you were going, it would take about an hour to get there by bus. The biggest problems were unreliable bus times and long service cycles. If you are at the bus stop 20 minutes early and the busses come every 30 minutes, it shouldn't turn into an hour wait for the next bus. That happened more often than I care to remember. I ended up bicycling when possible because it was faster.
If you can afford auto insurance, and if your time has any perceptible value, cars are still the best deal going. Even with gas at $4.50 a gallon, cars are by far the most efficient way to get around. It's not about laziness. It's about a reliable 20-minute drive to work instead of an unreliable 75-minute commute that includes waiting for 40 minutes in the cold/rain/heat.
it will be only a matter of time before uncareful drivers will step into their cars and hear a message: "Driving is wrong!".
If ever a story on /. qualifies for a car analogy, this one should. Sadly, I can think of none. RATS!
