PRT is not a serious option for urban public transit.
It has zero potential for being a primary, mainline, mode and the cost of the system would preclude it from being any sort of feeder system. The network-based guideway system would require immense amounts of elevated infrastructure and stations. The very attractiveness of PRT, which is personalized vehicles, utterly limits the system carrying capacity to a point where the economics of a project narrow to just a handful of potential applications, such airports, amusment parks, and perhaps large campus environments.
Also, the PRT vision of slim, attractive guideways would just not be possible in today's world where passenger safety for mass transit systems require the ability for people to exit vehicles in an emergency. The lightweight steel guideways of PRT would instead end up looking a lot like our SkyTrain system with concrete construction, walkway guardrails, large emergency exit stairs at stations, and the vehicles themselves would likely have to be designed to allow the ability for passengers to exit in an emergency. The vehicles would likely get larger as a result and before you know it you simply have a low-capacity people mover, which still isn't a viable rapid transit system.
