The Electronic Route Guidance System (ERGS) is the result of an effort to develop a new concept for guiding the motorist. To implement the concept a system has been developed which makes use of electronic equipment both in the participating vehicles and at intersections which are to supply guidance instructions. The system is destination oriented. The driver enters a code word representing his intended destination into the vehicle equipment. Then, as the vehicle approaches each instrumented intersection, the destination code is transmitted to the roadside where it is decoded according to a stored program and a routing instruction is transmitted back to the vehicle. In the vehicle the routing instruction is displayed to the driver in the form of a symbol or word message which gives the maneuver the driver should make at the upcoming intersection or interchange to reach his destination optimally. The report discusses the development of the system from its conception to its future application and benefits. It begins by describing today's highway routing problems in the static and dynamic situations. It then outlines the developmental effort and highlights the major contributions of its various contractors. (Author)
