车道被占用对道路通行能力的影响

The Effect on Current Capacity of Road When Vehicle Lane Are Occupied

通过对占用不同车道的车流量数据进行统计,分析了不同车道的实际通行能力变化过程,建立了交通流-密-速模型.并且通过建立微分方程模型,得到了受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函数关系.

By making analysis on the data statistics of traffic flow when different lanes are occupied, this paper explores the changing process of the actual capacity of different lanes, and establish the traffic flowdense-speed model. The functions of road vehicle queue length influenced by the traffic accidents actual current capacity of the accident section, accident duration, and section upstream traffic flow are obtained by establishing the differential equation models.
