Application of traffic movement display system to wall map display in ITS

The Nara Prefectural Police HQ developed and began operating a traffic movement display system. Unlike the conventional method of traffic condition display on a wall map which extracts traffic volume or flow data in time series and expresses its changing conditions from moment to moment as a quantity, this new system enables the spatiotemporally continuous expression of traffic volume or traffic flow. This paper introduces the traffic movement display system which is considered to be an effective means for an intelligent transport system (ITS) and discusses its applications to the wall map display including the identification and display of specific vehicles such as buses and trucks by making the best use of this system of information obtainable from infrared beacons which also perform a part of the ITS
