ABSTRACT:
A traffic information 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 system (10) includes a traffic light assembly (16) comprising 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).
