乌鲁木齐重点交叉口优化与仿真研究

Optimization and Simulation Research on Key Intersectionsin Urumqi

针对乌鲁木齐重点交叉口不同拥堵起因与拥堵类型,提出热点片区交通改善策略和重要通道交通改善策略,并主要以重点交叉口新华北路与光明路交叉口为例,实施交通组织优化,并利用VISSIM进行仿真。仿真结果表明,优化后交叉口运行状况得到明显改善,可为乌鲁木齐重点交叉口交通组织优化提供参考。

Aiming at the different causes and types of congestion at key intersections in Urumqi,this paper proposes traffic improvement strategies for hot spots and important passages,and mainly takes the intersection of Xinhua North Road and Guangming Road at key intersections as an example,implements traffic organization optimization and uses VISSIM simulation.The simulation results show that the operation status of the intersection has been significantly im⁃proved after optimization,which can provide a reference for the optimization of traffic organization at key intersec⁃tions in Urumqi.
