基于车头时距与行程时间的排队长度算法

基于电子警察过车数据,分析该周期内车道通行车辆的车头时距变化规律,提出该周期车道排队长度值的实时计算方法。针对多次排队、绿波协调情况,结合通行车辆的行程时间对结果进行修正,得到该周期车道最大车辆排队长度值。通过桐乡市庆丰路实时监控视频对比计算结果,证明本算法具有较高准确性。算法便于工程实践,可为信号配时优化提供数据支撑。

Queue Length Algorithm Based On Vehicle Headway and Travel Time

Taking the headway change rule of vehicles passing through the lane in one cycleinto account,a queue length algorithm based on electronic police data is proposed.For oversaturated lane and green wave situation,the vehicle travel timeis used to correct the results to get the max queue length valuein the cycle.Comparing the results with the data from the real-time monitoring video of Qingfeng Road in Tongxiang City,the algorithm is proved to be accurate.The algorithm is convenient for engineering practice and can provide data basis for traffic control optimization.
