摘要
对于复杂的交通流,传统公交信号优先有可能会破坏干线协调控制效果,为此,提出公交优先可变车速引导和多交叉口信号配时优化的集成方案.以背景公交线路需求的历史数据为前提,通过定时检测公交车流状况,优化公共周期、绿信比和相位差,实时调整多路口交通信号配时,以此改善公交车的通行效率.同时,以福州市金山大道三个交叉口为例,进行Vissim仿真模拟验证,仿真结果表明:所提方法可有效提升多交叉口公交车流的通行效益,减少公交车辆的延误,最大化减少停车次数.
Traditional bus signal priority may destroy the effect of coordinated control of arterial when the traffic changes greatly.An integrated scheme of bus priority considering variable speed guidance and multi-intersection signal timing optimization is proposed.Based on the historical data of background bus demand,bus flow condition is regularly detected to optimize the public cycle,green signal ratio and phase difference,which reassigns multi-intersection traffic signals in real time.By the way,taking three intersections of Jinshan Avenue in Fuzhou City as examples,Vissim simulation is carried out.The simulation results show that this method can effectively improve the traffic efficiency of multi-intersection bus flow,reduce the delay of bus,and maximize the reduction of stops.
