ABSTRACT:
An emergency vehicle sound-actuated traffic controller including an intersection of at least two roads with a plurality of traffic lights for directing traffic therethrough. The traffic lights have a conventional control box for the controlling thereof. Further provided is a microphone adapted to receive audio signals and further adapted to convert the audio signals to electrical pulses. Finally, control circuitry is electrically connected to the microphone and includes a switching mechanism. The switching mechanism includes a pair of contacts coupled to the control box. In operation, the switching mechanism has a first orientation with the contacts thereof open thereby allowing normal operation of the control box and the traffic lights and a second orientation with the contacts abutting each other thereby instructing the control box to direct all of the traffic lights to turn constant red. The control circuitry is adapted to shift the contacts of the switching mechanism to the second orientation thereof upon the instantaneous receipt of a siren of an emergency vehicle via the microphone. For safety purposes, the control circuitry is further adapted to initiate a timing sequence upon the instantaneous receipt of the siren of the emergency vehicle and further maintain the contacts of the switching gear in the second orientation thereof until the cessation of said timing sequence.
