Two Big Tests For Personal Rapid Transportation
Al writes "A novel kind of transit system, in which cars are replaced by a network of automated electric vehicles, is about to get its first large-scale testing and deployment. Two of these Personal Rapid Transit (PRT) systems are being installed this year, one at Heathrow International Airport, near London, and one in the United Arab Emirates, where it will be the primary source of transportation in Masdar City, a development that will eventually accommodate 50,000 people and 1,500 businesses and is designed to emit no carbon dioxide. The article examines these two systems and includes video that includes an animation of the PRT system in action."
I'm still a big fan of skytran. I don't know if the political and financial support is there but the economics seem reasonable and I think it's certainly an engineering possibility, not relying on unobtanium or anything wild.
The link to the website goes into far greater detail but the nickel synopsis is this:
1. Two passenger monorail cars using a computerized rail system to rapidly route passengers to destinations, avoiding the stop and start of traditional subway and light rail. (Monorail, yes monorail! Your simspon reference is weak, shut up.)
2. Cars, rails and towers are designed to be light so the footprint on the ground is about the same as a telephone pole.
3. With all the rails in the air, real estate on the ground can be used for pretty much anything, avoiding the disruptive problems and huge expense of running traditional light rail lines.
4. Because the lines are cheaper, a grid can be laid over a sprawling metropolitan area lacking the high population densities required to make traditional mass transit viable.
5. The goal is to have stops spread about everywhere so that where you want to go should be no more than a 15 minute walk after arrival. Current mass transit can leave you with miles to go to your destination.
6. Since the cars are electric and make no more than a whooshing line when going overhead, they would not be as disruptive as a conventional light rail train or a city bus.
The goal with skytran is not to replace cars but to take commuters off the road. Anyone as a single occupant in a car going places could be in one of these and free up the roads for people whose trips cannot be accomplished via skytran.

Of course, the real problem we're looking at here is that zero thought has been put into sustainable urban planning. We tend to ad hoc and half-ass everything together and end up with designs that are simply unworkable. But hey, that's the human way. Maybe the energy crunch can force a reevaluation of that.

The article (yes, I actually read it) actually compares the system to Morgantown's and why it should work better.
Bonus: You get to track exactly where everybody goes.

Generally, nothing. People love going on about this, but in every city I've lived in (Canberra, Sydney, Toronto, and London )the public transport has been clean. You're much more likely to run into disastrous misplacement of bodily fluids on the street.
