The Personal Mass Transit (PMT) system utilizes a removable vehicle conveyance apparatus and method for conveying transit vehicle car-pods and their contents from one transit station to another autonomously. Vehicle conveyance apparatus are stored off-line in storage silos and other areas awaiting on-demand transit system instruction to pickup vehicles at loading points and convey them to different stations as requested by occupants or pre-programmed instructions. The PMT system further utilizes a number of transmitter-receivers nodes and control computers to manage all aspects of operation of the transportation system. Any number of different types of PMT vehicles could ride the transit system when equipped with the correct coupling points and remain under the maximum combined curb weight of any particular area or type of transit track in order to be transported on the PMT system.
