ABSTRACT:
An electric vehicle transportation system. The system includes a roadway having a load bearing surface. The load bearing surface supports an electric power rail extending longitudinally on the roadway. The power rail is segmented and includes a plurality of longitudinally aligned, mutually electrically isolated portions. A power bus energizes selected portions of the rail. Energization is controlled by power switching controllers associated with each of the electrically isolated portions of the rail. Energization selection is effected in response to an actuation signal applied to a portion longitudinally displaced by a predetermined interval from the portion of the power rail associated with the controller which is connected to the controller by an actuation signal transmitting apparatus. Electric vehicles are adapted for operation on the roadway by being adapted to provide the actuation signal to a selected portion of the power rail and being further adapted to draw power from an energized portion of the power rail.
