摘　　要：从绿波协调控制需求与特点出发,针对协调优化的本质性原理展开研究。首先,创建了绿波轨迹特征点、特征线、特征方程与特征解的概念体系,提出了基于协调控制特性分析的绿波轨迹特征原理;然后,解析了面向绿波轨迹特征的协调控制周期特性、闭合特性以及叠加特性,结合匹配时间差特性分析,给出了协调路径绿波带宽损失计算方法与干道绿波协调设计目标函数;随后,根据绿波轨迹特征方程与协调设计类型,分析了绿波轨迹特征点集合的确定方法,给出了路段行人过街信号配时设计的约束条件,构建了面向绿波轨迹特征原理的干道绿波协调优化模型;最后,以广东省佛山市绿景路为例进行案例分析。结果表明:构建的模型能够获得较为理想的干道绿波带宽;相较于现状信号配时方案、MAXBAND、MULTIBAND以及SYNCHRO优化方案,所提出的模型优化方案能够有效地减少车辆平均延误时间与停车次数,取得较优的干道绿波协调控制效果。This study investigated the essential principles of coordinated optimization from the requirements and characteristics of corridor progression coordinated control.First,a conceptual system of the characteristic points,lines,equations,and solutions of the progression trajectory was created.Subsequently,the theory of progression trajectory characteristics based on coordinated control characteristic analysis was proposed.Second,the periodic,closure,and superposition characteristics of the coordinated control of the theory were analyzed.The calculation equations of coordinated path progression bandwidth loss and objective function of corridor progression coordinated design were given,along with the analysis of matching time difference characteristics.Third,the method for determining the set of progression trajectory characteristic points was analyzed according to the progression trajectory characteristic equation and coordinated design type.Constraints for road section pedestrian signal design were also provided.Subsequently,a coordinated optimization model of corridor progression with the progression trajectory characteristic theory was constructed.Finally,a case study of the Lvjing Road in Foshan City,Guangdong Province,was used as an example.The case study shows that the proposed model can obtain ideal corridor progression bandwidths.The VISSIM simulation results show that compared with the current signal timing scheme,MULTIBAND,MAXBAND,and SYNCHRO optimization schemes,the proposed model can effectively reduce the average delay time and number of stops.The proposed model can obtain better control of the corridor progression coordination.
