Abstract

Emergency vehicles' temporary control system for traffic lights. Emergency vehicles contain a short-range transmitter module (2) that sends out a code. A receiver-transmitter module (9) is included at each of the zone's distinct entrance points, so that the receiver-transmitter (9) situated at the vehicle's entry point detects the code and after verifying that it is correct, it sends out a new, different code that is detected by the receiver-selector (17) which identifies the activated receiver-transmitter module (9). Using the selector it then activates a programmed emergency plan in a conventional controller (27) so that this then operates the traffic lights (28 and 28') opening all the possible routes that the vehicle might take and closing the remaining routes that affect those that have been newly opened.
