A Far Infrared Vehicle Sensor for a Traffic Signal Control
This paper describes new type of vehicle detector that uses infrared technology to detect vehicles based on temperature differences. The authors describe the role of sensors for acquiring traffic congestion information and to control traffic signals. Their sensor, which uses a far infrared receiver element called a thermopile, can be powered by a solar cell battery. Also, it can detect vehicles from oblique directions, and therefore it can be mounted on a shorter mounted arm and is more aesthetically acceptable. The authors discuss the use of a profile signal control system, in which traffic signals can be controlled optimally even in the area where traffic situations change sharply according to the time of day or day of the week. They describe the use of this system in a model project of a real-time traffic signal control system in Kanagawa and Ehime prefectures, Japan.
