主辅路合流点设置预信号研究

Study on Pre-Signal Setting of Confluence Points between Mainline and Auxiliary Roads

本文主要通过对深圳市深南大道与竹子林四路交叉口东进口道现状进行调查研究的基础上,根据现状存在的问题以及交通流量特性,提出预信号优化方案,并利用vissim交通仿真软件对传统方案和预信号方案仿真评价,用量化的数据比较方案可行性,并通过vissim仿真实验得到预信号方案下主辅路交通组织模式的准入条件和设置标准.

This paper analyzed the existing conditions at the westbound approach the intersection between Shennan Avenue and Zhuzilin 4th Road in Shenzhen.Based on the existing problems and traffic flow characteristics,the pre-signal optimization scheme is proposed.The Vissim traffic simulation software is used to evaluate the optimization schemes.Based on the simulation experiment,pre-signal program access conditions and setting standards for the mainline and auxiliary road are obtained for managing traffic flows.
