摘 要: 以交通事故这种异常事件为例,分别对高速公路基本路段内交通事故影响时间、车辆排队长度、事故影响下不同时间段内不同路段断面流量变化进行了分析。采用交通波理论给出了该事故路段内不同时间段内不同阻塞行车道宽度的车辆排队长度,并对流量变化分析进行了仿真验证。 Taking a traffic accident, one of unusual traffic of the accident, vehicles queue length, and variation in traffic incidents, as an example, it analyzed time in effects flow of different cross-sections in different time slices in effects of the accident in basic freeway segments. Employing the traffic wave theory, it provided vehicles queue length with various widths of the blocked lanes in different time slices in effects of the accident in this basic seg- ment. Then variation in traffic flow is simulated.
