为实现干线协调控制，提升道路通行效率，减少交通延误，提出了干线协调控制方法。分析了周期时长、相位相序、绿信比及相位差等影响干线协调控制的控制参数，剖析了基于交通波理论的车辆排队特性。基于交通波理论确定相位差，在车路协同环境下对干线车辆进行车速诱导控制，为减少交通延误提高绿波协调效率提供理论依据。选取青岛市漓江西路3个交叉口为仿真场景，利用VISSIM进行仿真验证，优化后平均排队长度减少82.57%，延误减少32.25%。结果表明该控制方法明显减少了平均排队长度和延误。利用MATLAB对车速诱导模型进行仿真验证，结果表明车速诱导可提高通行效率。
Abstract：In order to realize the arterial coordinated control,improve traffic efficiency and reduce traffic delays,an arterial coordinated control method is proposed.The control parameters including cycle duration,signal phase,split and phase difference that affect the arterial coordinated control are analyzed,and the queuing characteristics of vehicles are also analyzed based on traffic-wave theory.In order to provide a theoretical basis for reducing traffic delays and improving green wave coordination efficiency,the phase difference is determined according to the traffic-wave theory,and the speed of mainline vehicles is guided and controlled in a cooperative vehicle infrastructure environment.Three intersections on Lijiang West Road in Qingdao are selected as the simulation scenarios,and simulation verification is carried out by using VISSIM.The average queue length is reduced by 82.57% after optimization,and the delay is reduced by 32.25%.The results indicate that the proposed control method significantly reduces the average queue length and delay.MATLAB is used to simulate and verify the speed guidance model,and the results indicate that the speed guidance can improve the traffic efficiency.
