Traffic speed surveillance system
First Claim
1. A traffic speed surveillance system comprising:
- vehicle transmitter means mounted in a vehicle and responsive to speedometer means for sending radio signals indicative of vehicle speed; and
monitor receiver means located along a roadway and communicating with central processor means, and receiving said radio signals for surveillance of traffic speed,wherein;
said vehicle transmitter means includes means for entering driver indentification and for entering vehicle identification, and transmitting radio signals indicative thereof;
said monitor receiver means receives said radio signals indicative of speed, driver identification and vehicle identification, for reporting such information to said central processor means; and
said vehicle transmitter means comprises run enable means operatively connected with said vehicle and disabling operation thereof without both said driver and said vehicle identification entry.

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.
