| | Personal Rapid Transit - Cyberspace Dream Keeps Colliding With Reality |
 | | A transit concept from the 1960s, envisioning tiny automated electric automobile-like vehicles speeding throughout urban neighborhoods on elevated guideways, Personal Rapid Transit has fallen on its face and seemingly died several times, only to be repeatedly resuscitated by its adherents. |
 | | While Personal Rapid Transit is usually presented as a brandnew, emergent concept, it is far from new, and indeed has a record of (troublesome) experience which provides valuable lessons helpful to evaluating critical elements of the PRT concept today. |
 | | Thus in suburban areas where a vehicle size for three to six persons would be optimal, construction of guideways is economically infeasible; on major arterials where guideways are justified, the small vehicles cannot provide the required capacity. |
