ABSTRACT:
A signaling and traffic control system which is capable of a vehicle determining its own absolute position along a guideway based on information received from the wayside using an inductive loop or beacon system in conjunction with the distance traveled according to the onboard tach generator(s), and report its position to a wayside control device, whereby the wayside control device reports to the vehicle, as part of its communications message, the location of the closest forward obstacle. Based upon this information, the vehicle controls itself safely based upon its characteristics as contained in a topographicla database and a vehicle database.
