ELECTRONIC MESSAGING USING VRC (VEHICLE TO ROADSIDE COMMUNICATIONS)

This paper describes an electronic messaging system (also known as in-vehicle signing) for IVHS (Intelligent Vehicle-Highway System) applications based on the VRC (Vehicle to Roadside Communications) system. Driver inattentiveness, poor visibility, and information overload all interfere with the driver's ability to read and acknowledge fixed message roadway signs. An electronic messaging system improves the present highway sign system by providing the message to the driver in the vehicle and by sending dynamic safety and warning information (such as railroad crossing, ice on bridge, high wind, deer crossing, etc.). Convenience information such as food, gas, lodging, intersections, and other items of interest can be provided. The VRC system using the TDMA (Time Division Multiple Access) protocol provides the infrastructure for the electronic messaging system.
