基于运行分析法的信号交叉口配时研究

Study on Timing Scheme of Signal Intersection Based on Operation-analysis Method

以锦州市人民街—延安路信号交叉口为研究对象,调查了该交叉口现有的交通信号配时参数及早高峰期间各进口道的交通量,采用运行分析法研究了该交叉口的合理信号配时方案,并对该交叉口信号配时方案的可行性进行了分析。给出了4个相位的绿灯时间,调整后,该交叉口关键车道组的v/C比及整个交叉口的极限比均小于1.0。

Taking the signal intersection of Jinzhou People’s street-Yanan road as the research object, the current timing parameters were measured and the traffic volume at early peak period was also investigated. Applying the operation-analysis method, the timing scheme was researched and the feasibility on the scheme was analyzed. 4 phase positions’ green light times are given, and v/C rate of the key lane group of this intersection to the limit rate of the whole intersection is all less than 1.0 after adjustments.
