交通干线协调控制与评价

Coordinated control and evaluation of traffic trunk lines

以内蒙古包头市团结大街为例,选取调查其中三个交叉口,分析现状,作出评价。采用干线信号协调的方法,基于最大绿波带宽优化相位差,取得各交叉口最佳信号配时,在早高峰形成出城方向单向绿波,平峰形成双向绿波。经过仿真分析在高峰期间东向西方向减少停车次数0.43次,各交叉口平均减少延误17.79 s/veh;平峰期间双向平均行程车速提高6.95 km/h,提升25.42%。

Taking Tuanjie street in Baotou city of Inner Mongolia as an example,three intersections are selected to analyze the current situation and make evaluation.The main line signal coordination method is adopted to optimize the phase difference based on the maximum green wave bandwidth to obtain the optimal signal timing of each intersection.The one-way green wave is formed at the morning peak and the two-way green wave is formed at the flat peak.After simulation analysis,the number of stops in the east-west direction is reduced by 0.43 times during the peak period,and the average delay of each intersection is reduced by 17.79 s/veh.During the peak period,the two-way average travel speed increased by 6.95 km/h,increased by 25.42%.
