P ersonal rapid transit, or PRT, seeks to bridge the gap between the privately owned automobile and public rapid transit systems. In a typical PRT system, a patron would purchase a card which would act as a key or ticket providing access to a vehicle owned by the transit agency. This vehicle would be propelled on the systemís complex network of tracks to a chosen station, not stopping at any stations enroute. In some systems, one may even disengage the vehicle from the tracks and drive it on surface streets, parking it for the day at work or overnight at home.
