大型Y型交叉口二次停车模型及其应用分析

Study on the Large Y-shaped Intersection Secondary Starting Model

针对大型Y型交叉口信号控制优化问题,以福州市华林路-六一路交叉口为研究对象,结合交叉口信号控制相关成果,对交叉口的交通组织、信号相位相序、信号配时等进行设计,建立了大型Y型交叉口二次停车模型,并应用VISSIM交通仿真软件对优化前后的交叉口交通运行进行评价分析。仿真结果表明:采用二次停车控制方式后,交叉口的车辆平均延误和车辆平均行程时间均有下降,所建模型具有良好的预期效果。

In order to optimize the large Y-shaped intersection signal control, the intersection of Hualin Road and Liuyi Road in Fuzhou was used as a study object in this paper. According to relevant results about the intersection signal control, the traffic organization, signal phasing-sequence and signal timing at signal intersection were designed to to make a large Y-shaped intersection secondary starting model. And evaluation of the intersection traffic operation before and after the optimization was performed in VISSIM Traffic Simulation Software. The simulation results showed that after the adoption of secondary starting control, the vehicle average delay and average link travel time at the intersection both decreased and the model reached an expectant result.
