VISSIM在城市平面交叉口交通改善评价中的应用

该文运用交通微观仿真技术对城市平面交叉口的改善方案进行评价,从渠化设计、信号控制等方面对停车延误和排队长度进行了交通仿真的应用研究,采用德国VISSIM仿真软件对某城市平面交叉口改善方案进行了实例分析。研究表明,交通仿真技术用于平面交叉口改善方案研究具有定量化、形象化的特点,可以客观地评价方案的优劣,并为方案的进一步改善提出建设性意见。

Application of VISSIM in Evaluating Transportation Improvement at Urban Plain Intersection

The article applies the traffic' microcosmic simulation technology to evaluate the improvement scheme of the urban plain intersection,studies the traffic simulation of the stop delay and queue length from the aspects of the channelization design and signal control.In the article,the Germany VISSIM simulation software is used to analyze the case of an urban plain intersection improvement scheme.The study makes clear that the traffic simulation technology used for studying the plain intersection improvement scheme has the quantifying and visualizing characteristics.It can impersonally evaluate the advantages and disadvantages of the scheme and puts forward the suggestions for further improving the scheme.
