  • Patent number: 4688487
    Abstract: A vehicle transportation system which includes a self-propelled vehicle for propulsion along a track through a plurality of predefined sequential track zones. The vehicle receives power and control signals from a plurality of electrical buses which are positioned adjacent to the track and extend through the track zones. The buses for indicating presence of a vehicle within a zone and for arresting vehicle motion, as well as one of the velocity control buses, is segmented or discontinuous between adjacent zones, and bus segments are directly electrically connected or jumpered between adjacent zones for controlling vehicle motion and avoiding collision with a stalled vehicle.
