面向潮汐交通流的信号控制策略优化

Strategy optimization of signal control for the tidal flow

为缓解城市潮汐交通道路的拥堵程度,提高道路通行效率,以青岛市黄岛经济技术开发区滨海大道为例,综合考虑道路沿线用地性质以及远景规划方案,结合单点交叉口配时方法以及考虑受车辆排队影响的相位差算法,采用分段绿波控制方式,并通过设置瓶颈控制适当缓解下游交通压力,实现车辆连续快速通过各交叉口.运用Vissim仿真软件进行交通仿真,对所得数据进行数理统计分析,结果表明该方法有效提高了道路的通行效率,缓解了潮汐交通拥堵现象.

In order to reduce congestion of tide traffic and improve travel efficiency, the paper with the Huangdao-Binhai Road of Qingdao as a case combines the means of single intersection timing and the phase difference algorithm, adopts green wave segmented control and bottleneck control to relieve traffic pressure and achieve vehicle pass the intersection quickly. It also uses Vissim to simulate and analyze the resulting dates by the mathematical statistics method, the result proves that the means can improve traffic efficiency and relieve the traffic congestion phenomenon.
