摘　　要：通过传统交通可测参数和移动终端采集到的交通数据,分析交通事故发生前后交通流的变化,根据移动终端采集道路上下游检测的数据,将实时采集的交通数据与正常交通情况下交通时间进行比对,超过交通时间未被下游检测点检测到的车辆数超过设定的阀值,则推算出上下游间发生交通事故,再根据通过上游的车辆序列、上下游间原本的车辆序列及未过下游的车辆序列,计算出事故造成的车辆堵塞数;最后设计检测算法。实验结果证明,本方法具有一定的可行性,能够适应道路交通状况。Based on the traditional traffic measurable parameters and the traffic data collected by the mobile terminal,the traffic flow changes are analyzed before and after the traffic accident.Compared the traffic data collected in real time with the traffic time under normal traffic conditions.If the number of vehicles that are not detected by the downstream detector larger than the set threshold,the traffic accident will occur between the upstream and the downstream,then according to the sequence of the vehicle passing through the upstream and the downstream,the number of vehicle jams caused by the accident was calculated.Finally,the algorithm of the detection method was designed.The experimental results show that the method has certain feasibility and can adapt to road traffic conditions.
