Claims13
A road speed control system comprising:
- roadside transmitter/receiver members for positioning along roadsides where speed limits on roads change;
- a vehicle speed control assembly for disposing in a vehicle;
- and
- a monitoring and transmitting assembly for police;
- wherein each of said roadside transmitter/receiver members emits a radio wave signal upon a road, said radio wave signal indicating a maximum speed for that particular road, each of said roadside transmitter/receiver members including means for directing a respective said radio wave signal upon a portion of the road where the speed limit changes depending upon direction of the vehicle, each of said roadside transmitter/receiver members including means for receiving signals as to a speed of the vehicle.
