ABSTRACT:
A traffic control system comprising a traffic control strip extending along a traffic flow lane and having a plurality of luminants extending at spaced intervals in a linear fashion along the traffic control strip, a plurality of detectors positioned on the traffic control strip so as to detect vehicles passing in proximity thereto, a processor connected to the detectors and to the luminants in the traffic control strip. The traffic control strip is a clear strip of material rigidly affixed to the surface of the traffic lane. The traffic control strips include the electrical transmission lines extending from the detectors and the luminants to the processors. The luminants are a plurality of LEDs spaced in a linear array. The detector is an infrared transmitter/detector positioned at regular intervals along the traffic control strip. Vehicles passing along the traffic control strip may contain suitably positioned infrared transmitters and receivers for communication with the traffic control computers.
