ABSTRACT:
A vehicle speed and safety system includes a stationary transmitting device positioned on a side of a road for generating and transmitting a signal indicative of a speed limit for a respective portion of the road and a unit positioned within a vehicle. The unit includes a receiver for receiving the signal indicative of a speed limit from the transmitting device. A microprocessor analyzes the received signal to determine a posted speed limit represented by said signal, monitoring a speed of the vehicle and compares the determined speed limit to the monitored speed. A display generates an alarm signal when the microprocessor determines the monitored speed exceeds the speed limit. The signal indicative of a speed limit is preferably transmitted at a frequency unique to the speed limit whereby each frequency represents a 5 mile per hour group of speed limits.
