城市道路交叉口交通组织优化与评估

Optimization and Evaluation of Traffic Organization at Urban Road Intersection

选取昆明市青年路—威远街交叉口为例,在现状运行分析的基础上,对交叉口组织方案进行优化,通过仿真手段对优化后的方案进行论证,并以最大排队长度、平均延误时间作为交通效益的评价指标,验证研究范围内不同路段道路服务水平及上下游交叉口运行情况。研究成果能够为城市道路交通组织优化分析提供参考。

Taking the intersection of Qingnian Road and Weiyuan Street in Kunming City as an example,based on the analysis of its current operation situation, the intersection organization scheme was optimized. The optimized scheme was demonstrated by simulation tools, and then selecting the maximum queue length and average delay time as the evaluation indexes of the traffic benefit, the road service level of different sections and the operation of upstream and downstream were verified and studied. It can provide reference for the optimization and analysis of urban road traffic organization.
