摘　　要：目前的干线自适应协调控制研究大多是基于历史交通流数据进行预测或离线优化等方式,如国外的SCOOT系统以短时预测到达停车线交通流进行小步渐进寻优、SCATS系统以离线预先设定多套方案以匹配实测交叉口不同饱和度值。在我国,对于城市的路段出入口多、转向交通流量多变的交通干线,很难较好地匹配实时变化的交通通行需求。通过分析城市交通干线通行不均衡特性,充分考虑干线绿波通行效果和干线各交叉口内部自适应优化的需求,建立了干线自适应协调动态迭代优化模型,通过对协调干线各交叉口的运行周期、绿信比、相位差等全量参数进行多次迭代的方式,使当前的信号控制方案更好地匹配实时交通流的变化。实地应用表明:模型能够使干线协调方向平均行程时间大幅缩短,通行效率得到明显提升,干线中各交叉口的小时通行量和绿灯利用率也有显著改善,对我国城市交通干线协调控制具有广泛的适用性。Most of the existing research on arterial adaptive coordinated control is based on historical traffic flow data for prediction or offline optimization.For example,the SCOOT system uses short-term prediction to gradually optimize the traffic flow reaching the parking line,and the SCATS system utilizes offline pre-set multiple schemes to match the measured intersection saturation values.In the practical application of traffic arterial with multiple entrances and exits and variable turning traffic flow in Chinese cities,it is difficult to match the real-time changing traffic demand well.The uneven characteristics of urban transportation arterial are analyzed.The effect of green waves and the need for adaptive optimization at each intersection are fully considered.Moreover,a dynamic iterative optimization model for arterial adaptive coordination is established.The current signal control plan can better match the changes of real-time traffic flow by iterating the full parameters such as operating cycle,green signal ratio and phase difference of the intersections of the coordinated trunk line.The applications show that the proposed model can significantly shorten the average travel time in the coordinated direction of the arterial,improve traffic efficiency,and markedly enhance the hourly traffic volume and green light utilization rate at various intersections in the arterial.Conclusively,the model has wide applicability to the arterial coordinated control in China.
