For those of us in the UK who'd like to read an article about a UK airport written by a UK media organisation... http://web.archive.org/web/20140912134733/http://www.bbc.com...

I'm pretty infuriated that I can't access this.

Wait until evading the license fee becomes a civil offense.

This is one of these things where instead of an article with a bunch of pictures, someone should have just turned on his smartphone camera and done a video of using one.

You know, like this: https://www.youtube.com/watch?v=C7OxvLuK83g

PRT has a checkered image. Transit planners dislike PRT and its advocates for a number of reasons. The big one is that in principle, modality isn't key to providing mobility - you can get it from a car, a bus, or a rail system as long as each of those things reach destinations you're interested in with appropriate frequency and capacity; the sustainability of the system is a measure of how the system is planned, as much as it is the modalities it encompasses. If your city is such that everyone commutes in big morning and evening rush hours to known "downtown" destinations, you can already plan the capacity and routes around that with adjustments to bus and train schedules. In turn this intersects with other urban planning goals around how to develop the city as a whole - transit guides zoning and zoning guides transit, and those things aren't easily separated.

So when PRT boosters come in and proclaim a silver bullet by switching modality, skepticism is natural. I think the technology is worthy myself(and I was more strongly for it once upon a time) but it has to be a fit for the overall policy, and this explains why its foothold has been in airports, where a very easy case can be made for 24/7 on-demand capacity. A PRT-centric policy at the city level would imply that everyone wants to go to arbitrary destinations at any time of day, which is purely a win for any individual rider, and probably is ideal for cities in general, but rings false for a planner dealing with the here-and-now.

If the efficiency claims are true, it's pretty awesome. There is a lot of public transportation that fails to be more efficient than cars because it is high-latency, failure prone, and doesn't handle peak and off-peak demand well. Imagine replacing Boston's Green Line with a system like this. Always a pod to take you to whichever branch you want to go, now.

What that statistic misses is the fact that the pods only cover the last mile between medium-term parking and the terminal. Users still have fro drive all the way to Heathrow to tai advantage of the cost savings (and drive past the terminal for anther mile to park and get the pod back again). Meanwhile the overpriced 'short stay' parking sits half empty.
