摘要
为提高城市干线机动车通行效率,改善道路交通出行环境,对城市干线信号控制交叉口采取双向绿波协调控制.基于Synchro软件和Webster信号配时方法,运用交通流理论对干线绿波协调控制系统中交叉口的配时方案进行优化,通过仿真建模得出信号相序和双向绿波带宽优化方案.在深圳市鹏飞路8个信号交叉口进行实际应用,采取跟车法现场采集优化前后绿波协调控制路段的双向绿波行驶时间、停车次数等相关数据,经分析发现双向总行程时间下降43.5%,平均停车次数下降71%,取得良好的社会经济效益.
In order to improve the efficiency of motor vehicles and the environment of road traffic,two-way green wave coordinated control was adopted for signal-controlled intersections of urban trunk lines.Based on Webster signal timing method and Synchro simulation software.The timing scheme of intersection in trunk green wave coordinated control system is optimized by using traffic flow theory.The signal phase sequence and bidirectional green wave bandwidth optimization scheme are obtained through simulation modeling.It is applied in 8 signalized intersections of Pengfei Road,Shenzhen.The following method was adopted to collect and optimize the bidirectional green wave driving time and parking times of the green wave coordinated control section.The analysis shows that the two-way total travel time decreases by 43.5%.The average number of stops dropped 71%.Good social and economic benefits have been obtained.
