Abstract
Abstract A transportation system that uses bus-like tire vehicles that travel in an express trackway between the suburbs and the city. The bus-like vehicles also have the capability of driving on conventional roadways in the suburbs and the city for picking people up and dropping them off close to their homes and offices. The bus-like vehicles are electric motor driven so that the motor may receive electric power either from the trackway when the vehicles are on the trackway or from batteries carried by the vehicles when they are off the trackway.
