For Japan, the development of intelligent transportation systems (ITS) is a necessity in order to resolve traffic congestion and other transportation problems of a country with a population density almost 12 times greater than the United States. This article begins with the history of ITS in Japan, the United States, and Europe, and defines ITS on two levels. The first level deals with ITS as a transportation revolution. The second, more global, level views ITS as a leading model for information technology applications in general. Japan's approach to ITS is described as part of a global advanced information and telecommunications society. The National Police Agency produced "Basic Government Guidelines of Advanced Information and Communications in the Fields of Roads, Traffic and Vehicles," which promotes ITS research and development and integration of individual projects into one coherent ITS program. The article highlights Japan's ITS development projects in the areas of navigation systems, automatic toll collection systems, safe driving assistance, and optimization of traffic management. |
