The invention relates to an intersection signal control optimization method based on a travel time relation function, and relates to the technical field of signal control. Individual vehicles are orderly connected in series in the whole process of entering a research road section, driving rules in the road section, parking and queuing and passing through an intersection, the space-time distribution condition of the individual vehicles in the road section can be accurately described, and after a travel time relation function is constructed, the relation between travel time and intersection signal control is considered, so that the time-space distribution condition of the individual vehicles in the road section can be accurately described. The minimum average travel time of all individual vehicles passing through the intersection under a certain set signal control scheme is used as a target function, an intersection signal control optimization model is constructed for intersection signal control optimization, and the vehicle passing efficiency of the intersection is improved.
本发明涉及一种基于行程时间关系函数的交叉口信号控制优化方法,涉及信号控制的技术领域,通过构建信号控制路段车辆个体的行驶时间计算模型和排队时间计算模型,将个体车辆从进入研究路段、在路段中行驶规律、停车排队、通过交叉口整个过程有序串连,能够准确刻画出个体车辆在路段的时空分布情况,在对行程时间关系函数构建后,考虑行程时间与交叉口信号控制的联系,以通过交叉口所有个体车辆在某一设定信号控制方案下的平均行程时间最小为目标函数,构建交叉口信号控制优化模型用于交叉口信号控制优化,提高交叉口的车辆通行效率。
