城市道路干线优化设计及仿真研究

Research on optimization design and simulation of urban artery

以郑州市东风路干线上的东风路-政七街、东风路-经三路和东风路-东明路三个交叉口之间的路段作为研究对象,调查交通现状,在完善标志标线,对车道进行合理划分的基础上,运用交通控制原理和PTV Vistro软件优化交叉口信号配时,并进行干线信号协调控制方案设计。利用PTV Vissim对优化方案进行仿真与评价,结果表明干线协调方案优化效果明显。

This paper takes the sections of Dongfeng road and Zhengqi street,Dongfeng road and Jingsan road as well as Dongfeng road and Dongming road on the main line of Dongfeng road in Zhengzhou city as the research objects,and investigates the current traffic situation,on the basis of improving sign marking and reasonable lane division,the traffic control principle and PTV Vistro software is utilized to optimize the signal timing of the intersection and achieve trunk line coordination.By simulating and evaluating the optimization scheme with PTV Vissim,the results show that the optimization effect of the trunk coordination scheme is obvious.
