基于VISSIM的五棵松交叉口改善评价

Improvement and evaluation of the Wukesong intersection based on VISSIM

以北京市西四环中路辅路的关键交叉口—五棵松桥下交叉口为实例进行交通组织状况分析以及优化仿真研究,力求改善五棵松桥下路口的交通现状。通过对交叉口道路状况和交通实地调查、整理和分析,分析其交通特点,并根据实测数据进行仿真,根据仿真结果分析其交通拥堵问题产生的主要原因,提出相应交通组织设计方案或优化方案,采用VISSIM交通仿真软件对相应方案进行优化仿真和评价,确定治理交叉口拥堵和混乱的最优方案,达到改善交叉口交通状况、提高交叉口通行能力的目的。

Taking the key intersection of the West Fourth Ring Road in Beijing--Wukesong bridge inter - section as an example , this paper analyzes the traffic condition and studies the optimal simulation, and tries to improve the traffic situation of this place. Based on field investigation, organization and analysis of its road condition and traffic flow, this paper analyzes its traffic features. According to the measured data simulation, the main reasons of traffic jam are analyzed , and puts forward corresponding traffic organization design or optimization schemes, and then using traffic simulation software - VISSIM to optimize simulation and analyze the corresponding schemes, and get the optimal scheme to treat traffic jam , so as to improve the traffic situation and increase the capacity of the intersection.
