| 摘 要： | 结合两段具体的视频分析同一横断面交通事故所占车道不同对该横断面实际通行能力影响的差异；然后着重探讨视频1中交通事故所影响的路段车辆排队长度与事故横断面实际通行能力、事故持续时间、路段上游车流量间的关系，从而构建数学模型；最后给出车队消散时间的表达式。

| Abstract: | The differences of influence of the same cross - section caused by different lane accidents for traffic capacity were analyzed based on two sections of video. And then the relationship among the vehicles queue length, the traffic capacity of cross- section, accident duration and theupper-road traffic flow in video 1 was mainly discussed. Accordingly, the mathematical model was formed. Finally, computational formula of the vehi- cles dispersing time was given. |
