ABSTRACT:
A transportation system comprising a plurality of driven vehicles movable along a track and controlled by the provision of deterministic cells, defined by track-to-vehicle speed and/or position command signals, which move along the track, each vehicle being confined within the limits of a cell but being capable of autonomous movement relative thereto to permit the formation of a contact train with other vehicles within the cell. A control is provided to close-up vehicles within a cell, and there may also be provided on board each vehicle three coordinated closed-loop subsystems, governing respectively the vehicle speed, position and closing speed relative to an adjacent vehicle.
