MISC | Personal Rapid Transit (PRT)

Has everyone heard of Personal Rapid Transit (PRT)? If not, learn about it. It will soon revolutionize transit and the urban landscape. It has big implications for central business districts and of course the sky scrapers in them. No other transit system can match it.

I've heard about this (I think!). I believe CNN did a report on this sometime ago, it was in Minneapolis.

Profitability

The groundbreaking ridership levels achieved by SkyWeb Express will generate farebox recovery ratios exceeding 150%. Expenses are lower, since automated operation removes the largest operational costs, and the system has been designed for ease of maintenance and repair. Advertising revenue increases through use of the display screen onboard. The combination of increased revenue and lower costs can result in a self-sufficient system requiring no subsidy for operations or construction.

-from the SkyWeb website

but don't take it from them. Independent studies have confirmed all this.

Yet apart from a few theme parks and demonstration systems non have been built. This concept has been hanging around since the sixties.

So there is a theme park using PRT? Which one?

PRT is a type of automated people mover - APM system (the one use in many airports around the world) - basically it is designed like a personal taxi but operated on a guideway. It follows concept of car pooling but works like an elevator if you know what I mean.
The idea is that each of these vehicles (which fits between 4-6 people) operates on a fixed guideway and can pick up and drop off passengers at stations along a designated route. Many experts say this form of transit is more suitable for low density cities like LA, Houston or a large building complex like university, defence compound etc. The advantage of PRT is obviously the relatively cheaper investment and operational costs (in theory anyway) compare to other form of transit such as light rail, metro. The PRT system can be designed such system to serve low density area in the suburbs, where it may not be economically feasible to build or extend a light rail, bus routes or whatever...plus you can design it so that it runs through building, university, shopping centers.

Many PRT prototypes are underdevelopment in US, Germany, France, Japan and Korea. Actually one of the leading developers of PRT is the American company Raytheon Corporation whose main expertees are in defence technology I did some background research on various PRT systems for one of my uni assignment, comparing this and a Light Rail System.

There was a proposal a few years ago to build one this system in Sydney.. using slightly larger vehicles called GRT (Group Rapid Transit).
Another site to check out is Skytran Technology's - http://www.skytran.net

here's some computer renderings of their system:

PRT would be a pretty unexciting thrill ride, since it would not careen around with drastic changes in elevation or g forces.

Before anyone makes up their minds one way or another about PRT, I encourage you to review some of the literature written by people who know and understand the PRT concept. It is not like a train, nor is it like the automobile. Most of all, it is not a joke or The Jetsons. Here are some places to start reading:

http://gettherefast.org (contains direct rebuttals to skeptics linked in Post 13)
http://kinetic.seattle.wa.us/prt
http://cprt.org
http://cities21.org
http://skywebexpress.com
http://atsltd.co.uk

I'm new to this forum, I look forward to a robust and friendly exchange.

Light Rail Now! pans anything that doesn't have steel wheels and a pantograph!

In one of the previous posts in this thread, a link is provided to the remarkable website of an organization called Light Rail Now!. If you read the Light Rail Now! article on PRT, you will see that:

1. The West Virginia University (WVU) PRT carries 16,000 riders per day when school is in session. (Actually, Light Rail Now! neglects to report this fact.)
2. The WVU PRT covers its own operating expenses.
3. The WVU PRT extends for 3.6 miles.
4. The cost to build the WVU PRT in current dollars is $89 million per mile for a fully grade separated route.
5. The WVU PRT is a FAILURE!

Light Rail Now! has also blessed us with an article concerning the new streetcar system in Tacoma, Washington. If you read the article, you will find:

1. The Tacoma streetcar carries 2,170 riders per day.
2. The Tacoma streetcar collects no fares and covers none of its operating expenses.
3. The Tacoma streetcar extends for 1.6 miles.
4. The Tacoma streetcar cost approximately $50 million per mile to build for a route that sits in the middle of a downtown street.
5. The Tacoma streetcar is a SUCCESS!

So, the WVU PRT is a failure and the Tacoma streetcar is a success. Go figure!

The Morgantown PRT is actually an AGT or Automated Guided Transport. It's really a variation of the familiar "people mover" you see in airports. The PRT people have disowned it, I suspect because its ugly concrete guideway and its cost overun. They also disown the Raytheon prototype PRT for much the same reasons.

PRT is really a cult:

I'm not seeing how PRT could carry significant numbers of people without major major infrastructure. This Group Rapid Transit seems much more capable though. Basically just higher frequency LRT that adapts to where people want to go and how often.

Otherwise it looks like it would end up much like a taxi rank, with a long wait for a vehicle.

I like the cartoon..
I really do think the potential of PRT is worth further investigation though.. especially how such a system can be designed to integrate into an urban environment.

I think the main infrastructure cost would be construction of the guide rails but I know there's a system being developed in Korea at the moment where these vehicles can run on rubber wheels on roads as well as on steel rails.
yeh they should make the vehicle a bit bigger... I'd say like a minivan.

To be basically a car replacement you would need it to at least accomodate disabled people and those with some sort of luggage.
