| | PUBLIC ROADS On-Line (Autumn 1996) - Intelligent Transportation Systems in Japan |
 | | Japan, with a population density almost 12 times greater than the United States, has an abiding interest in developing intelligent transportation systems (ITS) to resolve its traffic congestion and other transportation problems. |
 | | Now, Japan also seeks to enhance safety, comfort, and the environment through the use of the most appropriate means of traffic management, including signal controls, traffic information to in-vehicle units, priority to public transit vehicles, dynamic route guidance systems, monitoring commercial vehicles, better detour information, and controlling signals to reduce traffic pollution |
 | | The approximately 250 kilometers of metropolitan expressways contain a total of 2,077 vehicle detectors to measure the number of passing cars and their speeds, 862 television cameras, and 456 information or graphics displays. |
