Today's field trials, deployments, and pro's and con's of infrared (IR) beacon communication are discussed. During the early eighties, first concepts for dynamic route guidance systems appeared in Europe, the USA and Japan. In Germany, the newly founded private company for route guidance and driver information services COPILOT has already deployed IR beacons in Stuttgart and Berlin. Operational field tests with IR beacons are also being performed in the USA. Furthermore, in the German electronic toll collection field trial qualified technologies compete in a multi-lane, free-flow, and high speed environment. Siemens participates with its Chip Ticket System relying on IR communication between roadside and vehicles. The systems in place have a central road map data base, a central traffic data base as well as a central routing computer. The map data base is updated by an operator and real-time traffic data are received from participating vehicles acting as probes. In other words, there is an automatic real-time up-date of the traffic data base. Shortest routes in time are calculated and updated every 5 minutes in the central routing computer for each and every origin/destination relationship. They are transmitted via the IR beacon network to the vehicles. As a function of the programmed destination by the driver the in-vehicle-unit selects the O/D relationship or vector chain leading to the desired destination.
