车道被占对道路通行能力影响的定量分析

针对车道被占对城市道路通行能力影响的问题,以差异检验、排队论、车流波动论为基础,求得了事故横断面实际通行能力的变化过程.利用队列分析模型,分析对占道不同的实际通行能力,建立基于车流波动理论的排队长度模型,求解出了排队长度与通行能力、持续时间、上游车流量的关系.

Quantitative Analysis of the Impact of Lane Occupancy on Urban Traffic Capacity

Focusing on the impact of lane occupancy on urban traffic capacity, we obtained the change process of the actual capacity of the accident cross section relying on differences testing, queuing theory and traffic flow wave theory. By means of-queue analysis model, we analyzed the actual traffic capacity of the lanes. And then by establishinga queue length model depending on the traffic flow wave theory, we found the relation between queuing length, the traffic capacity, duration and up-stream traffic.
