ABSTRACT:
A control system is proposed which is capable of controlling driverless vehicles running on a fixed guideway according to schedule or demand. An input device is disposed at each station along the guideway to enable each passenger to enter his destination. A command and control center is in communication with the vehicles on the guideway and all the input devices. The center receives from each of the input devices simultaneously destination information and the identity of that one of the input devices providing the destination information to provide start information. A memory arrangement in the center contains control information for standard and diversion routes for all possible start-destination relationships. A computer arrangement in the center determines from all input information from the input devices whether the transport system should operate in a demand or scheduled mode at that moment in view of given operating criteria. An arrangement in the center communicates operating commands to each of the vehicles. The operating commands are a sequence of stored control information for standard or diverse routes and correspond to the mode of operation as determined by the computer arrangement.
