A FIELD DEMONSTRATION OF VEHICLE TO ROADWAY TWO WAY COMMUNICATION

This paper is a summary experimental design of the Inductive Loop Radio ( INRAD) project currently taking place at the California Polytechnic State University in San Luis Obispo. INRAD was designed to test the functionality and utility of two way vehicle to roadway radio communication in highway operations. Loop detectors installed in the pavement to perform standard vehicle detection would be also antennas for the exchange of information between specially equipped vehicles and a traffic operations center (TOC). All information coming from vehicles is gathered and messages conveyed in real time to a TOC facility. Loop specific information dictated by the TOC and relayed to vehicles as they cross the loop is also displayed to the driver on an alpha numeric in- vehicle display.
