ELECTRONIC ROUTE GUIDANCE BY AUTOGUIDE: THE RESEARCH BACKGROUND

Abstract

This paper outlines AUTOGUIDE, an electronic in-vehicle route guidance system for guiding drivers through London to their destinations. The information is given inside the vehicle and tells the driver the best route on the basis of up-to-the-minute knowledge of conditions throughout the London area. The number of users of the system and the traffic benefits that could result are calculated from estimates of the cost of the in-vehicle unit and a range of assumptions about purchase decisions. AUTOGUIDE consists of in-vehicle units which pass information to and from roadside units that are installed on the approaches to intersections. The roadside units are connected over the telephone lines to a central computer.
