基于固定检测器的区域交通状态判别方法
Method for traffic state identification based on fixed detector
摘要
Abstract
Models of state identification for road sections and intersections were established based on the basic traffic parameters which were captured by the fixed detector. Considering the different influences of road sections and intersections on the overall traffic status of the regional road network, models of weight calculation for road sections and intersections were established. On this basis, integrated models of traffic state identification for regional area were established. In order to classify the traffic states by the value of P, the relation between P and v was determined, and the traffic state was classified by P. A typical road network environment with nine intersections was designed in Vissim software, and the models were verified by the collected data. The results show that the methods constructed can effectively identify the traffic state of the urban area.关键词
