A traffic control system (10) including a road (12), a vehicle (14) traveling on the road (12) and a traffic light assembly (16) operatively associated with the road (12) is disclosed. The traffic light assembly (16) comprises at least one traffic light or lamp means (18). The traffic light (18) includes a plurality of light emitting diodes (24) for projecting light rays to the vehicle (14) to provide the driver of the vehicle (14) with a visual signal. The system (10) further comprises a transmitter (20) including a power supply (30) and a modulator (72) for turning the diodes (24) on and off at a rate that is imperceivable to humans while optically transmitting information to a receiver (22) disposed on the vehicle (14).
La présente invention a pour objet un système de régulation de la circulation (10) dans lequel une route (12), un véhicule (14) circulant sur la route en question (12) et un ensemble de feux de circulation (16) sont en association interactive. L'ensemble de feux de circulation (16) comporte au moins un feu de circulation (18). Le feu de circulation (18) comporte une pluralité de diodes électroluminescentes (24) servant à illuminer un signal lumineux à l'intention des automobilistes(14). Le système en question (10) comporte en outre un émetteur (20) relié à une source d'alimentation (30) et à un modulateur (72) pour assurer la mise sous tension et hors tension des diodes (24) à une cadence humainement imperceptible, tout en assurant la transmission de données à un récepteur (22) logé à l'intérieur du véhicule (14).
