Benefits of Dynamic Route Guidance Systems as Part of a Future Oriented City Traffic Management System 912832

In order to better cope with the future needs of traffic management systems an advanced route guidance and information system called LISB has been introduced and tested in the City of Berlin (West) (1). Infrared transmitters and receivers (beacons) are located at intersections of the main road network transmitting route recommendations to specially equipped vehicles. These vehicles measure their travel times per road section and transmit them via beacons to a central route guidance computer. Based on actual travel times, the central computer calculates the quickest routes in the network. These routes are indicated visually and audibly to the drivers, guiding them to their destinations, taking into account the actual and short-term predicted traffic situation.
Within a large-scale field experiment the system's performance, acceptance by the drivers, and benefits for the users as well as for the municipality have been investigated (2). The final results and a way of incorporating individual traffic control systems into traffic management systems will be presented in the following paper.
