基于排队论对车道被占用时道路通行能力的研究

Based on queuing theory lane capacity research of traffic capacity

本文以排队论为基础对车道被占用时的道路通行能力进行研究,应用排队论研究车道被占对道路实际通行能力的影响时也要考虑不同时刻经过被占路段上游的车辆数,应用泊松分布可以求出其概率。在对道路的通行能力研究的过程中,应用了SPSS软件技术对被占路段上游车流量的数据进行处理,得到不同时刻同一横断面道路通行能力的变化曲线。由于影响道路通行能力的因素有多种,进而应用多元线性回归原理分析道路通行能力与其诸多影响因素之间的关系。

The paper based on the queuing theory to study the traffic capacity of the lane occupied, lane occupied study on the application of queuing theory when the effect of the real road traffic capacity, also want to consider different time after occupied sections upstream on the number of vehicles, applied to calculate the probability of poisson distribution can be. During the process of research on road traffic capacity, we used the SPSS software technology of occupied sections upstream traffic data processing, get different time curves of the same cross - sectional traffic capacity. Because there are a variety of factors, which affect the traffic capacity, and then we apply the principle of multivariate linear regression analysis of the relationship between the traffic capacity and its many influence factors.
