Abstract
A traffic speed surveillance system is provided by a set of monitor transceivers (8, 10 and 12) located along a roadway (14) and communicating with a central processor (22), and including at least some stationary transceivers (8 and 10) sending radio signals indicative of speed limit in the location of the particular stationary transceiver. A vehicle transceiver (6) mounted in a vehicle (2) includes means for entering driver identification (36) and vehicle identification (48), and speedometer means (46) for measuring the speed of the vehicle. The vehicle transceiver receives the radio signals from the monitor transceiver indicative of speed limit and compares measured speed against the limit, and sends radio signals indicative of driver identification, vehicle identification and speed limit violation to the monitor transceiver for reporting to the central processor.
