IN-VEHICLE NAVIGATION REQUIREMENTS FOR MONITORING LINK TRAVEL TIMES IN A DYNAMIC ROUTE GUIDANCE SYSTEM

A dynamic route guidance system for automobiles and trucks operating on an arterial highway system was recommended recently to the Illinois Department of Transportation for testing and evaluation. The proposed system is the first among American Intelligent Vehicle Highway System (IVHS) demonstration projects to propose using vehicles equipped with navigation systems to monitor current travel time of the arterial streets comprising the highway network. In evaluating the feasibility of using vehicle probes in a demonstration, it was necessary to determine how many vehicles would need to be equipped to monitor link travel times adequately during peak periods. A traffic analysis assignment was essential as a basis for this determination. Using data from an adjacent study area, it was estimated that 4,000 navigation system-equipped vehicles would be needed for a 200 square mile test area. The analysis which formed the basis of this conclusion is described in this paper.
