Reduce Consumption : Produce Locally


Personal transit still a techno-dream

Ken Avidor, Seattle Post-Intelligencer, 23 August 2005

In recent years, there has been a lot of public discussion and debate (including a Friday guest column headlined "Lighten up on transit systems") about Personal Rapid Transit, or PRT -- particularly in Minnesota, where promoters have been trying to procure public funding for a starter project.

PRT proponents are masters at making extravagant claims and promises for this or that version of their techno-dream. However, it's important to recognize that PRT does not currently exist in successful public operation, and, in all likelihood, never will.

PRT has a solid 30-year record of controversy and failure. Its main purpose in recent years seems to have been to provide a cover enabling its proponents to spread disinformation about real, workable transit systems. Except for the occasional laboratory-scale prototype, PRT actually "exists" largely in computerized drawings, in promotional brochures and in cute, ever-successful animated simulations on the Internet.

The unsubstantiated claims of PRT proponents are always presented in the present tense as if the system is a success -- which, of course, it certainly is not. Promoters never seem to fail to bash real transit, such as light rail (LRT), as "old fashioned technology."

Sad to say, the media rarely check the veracity of PRT publicity and propaganda.

But, the truth is out there. In the 2001 OKI (Ohio-Kentucky-Indiana) Central Loop Study for metro Cincinnati, for example, the study's engineers (Parsons Brinkerhoff) found many serious flaws in the PRT design. That study cost the taxpayers in the Cincinnati area a cool $625,000.

There have been several attempts at building a PRT system over the years -- Morgantown in West Virginia, ULTra and Aramis in Europe, Raytheon's Rosemont, Ill., fiasco ... to name some of the more prominent examples. All have failed to live up to the claims of being "faster, cheaper, better" than conventional mass transit.

So if it doesn't work, why does it keep coming back for taxpayer funding year after year (as is currently happening in Minnesota and New Jersey)? What is PRT's real purpose?

Basically, PRT is a stalking horse for the highway construction industry. PRT proponents can say things that the highway boosters could never say, such as "People don't like to ride with strangers." This anti-transit propaganda divides and conquers the opposition to highway projects.

I saw this happen with the I-35W Access Project in Minneapolis. This is perhaps why the aggressive would-be PRT vendor Taxi 2000/Skyweb (until recently) had the support of, and shares a lobbyist with, SEH, the engineers for what many in South Minneapolis call the "Excess Project."

PRT was also used as an excuse by pro-highway/anti-transit Republicans in the Minnesota Legislature's 2004 session to block funding for the Northstar commuter rail line. This is why, perhaps, Taxi 2000/Skyweb Corp.'s leader, Ed Anderson, refers to PRT as a "disruptive technology."

The PRT flim-flam works the same way in other states as it has in Minnesota. PRT bamboozles and confuses citizens and lawmakers about the real, workable, off-the-shelf transit solutions that can help communities free themselves from gridlock, pollution and dependence on foreign oil.

And PRT promoters are experts at that kind of swindle. They seem to operate on the principle that there's a sucker born every minute -- especially among gullible journalists. Don't fall for the scam.

The next time you read a puff piece in the newspaper, in a magazine or on the Internet about PRT, let them know you don't buy their con -- write the publication or Web site and demand a real investigation of the PRT flim-flam.

Ken Avidor, of Minneapolis, Minn., describes himself as "perhaps the leading skeptic of Personal Rapid Transit."

It does not take a rocket scientist to realize that when nothing is moving, no energy is being used. Scheduled transit services must move at regular times whether they have passengers or not. They must also be sized to carry the maximum load during rush hour, regardless of how empty they are at 10 PM.

PRT would only move when something needed to be moved, so it is reasonable to think that it would be more efficient overall. Then there is the benefit of 24 hour availability and nonstop point to point travel. I think that we need a full investigation of the comparative energy efficiencies of "mass transit" versus PRT.

Mr. Avidor is on some kind of a personal vendetta against the future. I admire, however, his energy and his willingness to raise a subject that few people have even encountered (PRT). I agree with him that PRT (and its "flim flam") need a "real investigation".

In fact, I demand it.<\strong>

Here is the first in a series of point-by-point refutations of claims made earlier by Avidor, which he nonetheless makes again in the above opinion piece:

Much of this can be found in the feedback forum at the conclusion of the Seattle PI link, http://seattlepi.nwsource.com/opinion/237556_antiprtop.html

as well as the forum at the end of a pro-PRT editorial that preceded Avidor:

The best you can say about Avidor is that at least he's consistent... ly mistaken.
