Full disclosure: I am a passerby here. I have an academic interest in PRT and I follow PRT discussions when they pop up, and many of those discussions involve heated debates with Ken Avidor.
Ken Avidor would have you believe that PRT is a boondoggle and PRT promotors are anti-transit. Nothing can be further from the truth. Every PRT promoter I've ever encountered has a passion for public transit, and in fact, most are vehemently against sprawl and the car culture.
Ken would have you believe that PRT proponents are "crackpots", "PRTistas", "pod people" (his own derisive terms). He reinforces that stereotype by repeatedly highlighting PRT's conservative supporters in Minnesota - even though the main promoter in Minnesota was a bicycle riding Green.
On the contrary, PRT supporters come from across the political spectrum, from fiscal conservatives who like the financial viability of PRT, to environmentalists who like the reduced emissions, to transit supporters who want a solution that is fast and convenient. Don't be fooled into believing that it's some sort of anti-transit boondoggle - that is a complete fabrication.
To answer Ken's question: perhaps Debbie Cook is supporting PRT because the European Union has studied it extensively, and is moving forward as we speak with pilots in the UK and Sweden:
http://ec.europa.eu/research/environment/newsanddoc/article_2650_en.htmhttp://www.guardian.co.uk/technology/2007/oct/11/guardianweeklytechnologysection.news1?gusrc=rss&feed=travelIt seems Debbie Cook has examined the literature and sees past the propaganda of its detractors. Perhaps she read the studies that show PRT to be a more efficient solution than buses and light rail, even while providing vastly superior service. Or the fact that PRT has lower emissions per passenger than any other transport mode other than bicycling. Or that PRT would be vastly more convenient for transit riders (especially disabled riders) than any existing transit. Or that PRT is projected to operate without subsidy due to its efficient operational characteristics.
Ken Avidor is not pro-transit; he is pro-TRAIN. He has campaigned against every transit solution except light rail - buses, PRT, monorail, maglev. He is also associated with the Light Rail Now website, which is underwritten by light rail construction interests who would be threatened financially by PRT. Light Rail Now has campaigned heavily against PRT, and Ken Avidor has been a big part of that campaign.
