Paper Abstract

There are approximately 20 million police radar detectors used on the highways of the United States daily. A highway hazard safety warning system has been developed by the Georgia Tech Research Institute, working under the sponsorship of the radar detector industry, to communicate highway safety alerts to the driver of any vehicle equipped with a police radar detector. In addition, the system causes the new generation of detectors that are already available to display a safety warning message on an alpha-numeric display. The Safety Warning SystemTM consists of a transmitter and a radar detector receiver or stand-alone safety warning receiver/display system. The transmitter can be mounted on police cars, emergency vehicles, utility vehicles, highly repair vehicles, and on stationary structures at fixed locations along the highway. The reception range of the transmitted signal is between 0.5 and 1.0 miles, depending on terrain. The system to be described may be one of the first applications of in-vehicle signing in the Intelligent Transportation System to be implemented, because the required infrastructure of receivers already exists.
