摘要

出行时间是交通网络中衡量交通流量的尺度,是动态路线引导系统不可或缺的组成部分。采用基于体积平衡的非线性离散动态系统描述信号交叉口的队列长度和拥塞长度。根据城市交通网络中下游信号交叉口的拥塞分类、偏移控制和移动方向,分析了平均路段行程时间。通过交通流的平均速度来测量平均路段行驶时间,这是试验车技术之一。在此基础上,对福山市内三条线路的平均连线和OD时间进行了评价。在每个时间间隔内,将平均线路行程时间的评估值与测量值进行比较。

Evaluation of mean link travel time for urban traffic networks
Travel time is a measure of traffic flows in traffic networks and indispensable for the dynamic route guidance system. The queue length and congestion length are described by a nonlinear discrete dynamic system at signalized intersections based on the volume balance. The mean link travel time are analyzed according to the classification of the congestion, offset control and moving direction at downstream signalized intersections in urban traffic networks. The mean link travel time are measured by the average rate of speed of the traffic stream which is one of test-car techniques. The mean link and OD travel time are evaluated for three routes in Fukuyama city according to their analyses. The evaluation values of mean link travel time are compared with the measurement values for each time interval.
