基于仿真的畸形交叉口交通组织优化研究

城市道路畸形交叉口是交通冲突点较多、交通安全隐患问题突出、交通组织管理较为困难的一类平面交叉口,文章首先分析了城市畸形交叉口的主要形式和存在的主要问题,归纳了畸形交叉口交通组织优化的主要方法,并以唐山市卫国路—北新道—建华西道畸形交叉口为例,利用交通仿真软件进行了方案实施效果的评价,得出,对畸形交叉口进行交通渠化、信号控制、改变交叉口的形式等组织优化后可以明显改善交通运行状况,提高交叉口的交通运行效率。

Simulation-based Traffic Organization Optimization for Irregular Intersections

At irregular intersections there are usually more conflict points and traffic safety problems.Traffic organization and management of irregular intersections is,in general,more difficult.This paper firstly analyzes the main features and problems of the irregular intersections and summarizes the optimization methods for traffic organization at the irregular intersections.Then,it uses the intersection of Weiguo road-Beixin Road-Jianhua West Road in Tangshan City as an example and evaluates the implementation effect of the implemented schemes with a traffic simulation software Vissim.This paper concludes that such traffic organization optimization methods as traffic channelization,traffic signal control,and changing the intersection to a regular one,can significantly improve traffic movements and increase its efficiency.
