FUNCTION, EQUIPMENT, AND FIELD TESTING OF A ROUTE GUIDANCE AND INFORMATION SYSTEM FOR DRIVERS (ALI)
Usually, traffic flow is measured by induction loops which are installed under the road surface. An electronic unit on the roadside produces a weak electromagnetic field in the loop which is varied by vehicles passing over it. This variation is transmitted through a data line (telephone line) to a central computer. The incoming data are used for calculating a short-term prognosis. An improvement of the prognosis accuracy can be expected, if the destinations of the vehicles are known. This is the basic idea of the ALI system (guidance and information system for drivers). In return for indicating destination, the driver receives individual information about how to reach the destination in the shortest and easiest way. By knowing the destination, the system can improve its forecasting ability.
