摘要: 为解决路段下游线圈检测信息因受交通控制信号影响无法估计路段行程时间的问题,通过分析车辆在停车线处的动力特性,利用牛顿运动定律,对路段下游线圈检测车速进行分析修正,获取车辆通过停车线的修正车速.分析了车辆排队前部与其后车辆在通过下游检测线圈的不同运动特性,分段估计车辆通过路段的时间.用VISSIM4.20模拟软件设计实验,对比分析了基于路段上下游线圈检测信息进行的路段行程时间估计结果.实验结果表明,利用提出方法估计的结果较基于上游检测信息估计结果的准确性和稳定性均有提高.Abstract: Because of the influence of traffic control signals,speed detected by the downstream loop detectors can not be used to estimate road travel time.To solve this problem,based on the dynamic behavior of vehicles nearby the stop line,this paper analyses the downstream detected speed and modifies it by Newton motion law,and it discusses the different characteristics of vehicle speed between the head of the queue and the others,and estimates the travel time in different parts of the road section,respectively.The authors conducts an experiment using simulation software of VISSIM4.20,to analyses and compare the experimental results estimated based on upstream and downstream loop detectors.Compared with the estimated result based on upstream loop detectors,the result shows that the proposed method can improve the accuracy and stability of experimental results.
