車両感知器の設置位置効率化のための交通データ収集システムの分析

抄録

In this paper, we analyze highway detection system under different traffic scenarios. Traffic data collection depends on not only sensor technologies, but also where detectors are placed. Data validity highly varies on different traffic conditions and detection locations. To assess the detection efficiency, a generic data supply function is defined to describe detection system performance. In addition, speed data collection is selected as an example to determine a specific data supply function which depicts the relationship between speed detection variation and traffic state. The supply function is validated by a case study based on Tokyo Metropolitan Expressway.
