探究车道被占用对城市道路通行能力的影响

从车道占用对城市道路通行能力的影响入手,运用对比分析法、推理演绎法以及排队论等方法,建立道路通行能力模型、道路价值度模型、相关性分析模型、排队长度模型。并运用Matlab软件,得出所占车道不同对该横断面实际通行能力影响不同,车道被占用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,以及排队长度等结果。

Explore the Impact on Urban Road Capacity Caused by Lane Occupancy

This article starts from the lane occupied influences on urban road traffic capacity ,comparative analysis method ,reasoning deduction method ,and queuing theory are used to establish significant difference test model ,traffic capacity model ,the road value degree model ,correlation analysis model and queue length model. With the help of software such as Matlab ,EXcell,we obtained the differences in the results of occupied different lanes influences on the transverse section actual capacity . Draw a conclusion that the queue length influenced by occupied lanes relation-ships with accident cross-sectional actual capacity ,the duration of the accident and section of upstream flow. And the results of queue length.
