交通事故对路段通行能力影响作用分析

Analysis on Road Capacity of the Segment under the Influence of the Traffic Accident

摘要: 本文针对交通事故占用的不同车道，从道路横截面的车流量、车辆排队长度研究交通事故对城市道路通行能力的影响。通过从视频中截取事故道路横断面的车流量、路段上游车流量、路段车辆排队长度等数据，分析交通事故持续期间路段通行能力的变化过程，并分析当事故占用不同车道时，通行能力变化的差异及原因。

Abstract: The effects of traffic accident on road traffic capacity have been researched from some aspects in-cluding different lanes occupied, traffic flow of the road cross section and the length of vehicle queue. Some data after traffic accident has happened, such as the traffic flow from the upper section of accidence, have been collected to analyze the variation process of road capacity. Moreover, the difference and reasons of road capacity varying have been further studied when the different lanes have been occupied in the process of accident treatment.
