ABSTRACT:
A traffic control system for use at a roadway intersection, the system including traffic control lights, a light flasher structure, and a plurality of load switches electrically coupled with the lights via relay structure to which the flasher structure is connected, the load switches having inputs, and a controller connected with the load switches for controlling normal operation of the lights and flashing of one or more of the lights by the flasher structure in the event of a system malfunction comprising a microprocessor operatively connected with the load switches, flasher, and relay structure to monitor the system for detecting a malfunction event, for recording the detected malfunction event, and for transmitting the malfunction detection to another location; and verification structure at the other locations for i) receiving the transmitted malfunction detection, ii) verifying the event, and iii) initiating malfunction corrective action; whereby the corrective action in the system may be initiated without removing control by the controller of the operation of the traffic control lights at the intersection.
