The invention relates to the technical field of intelligent traffic association, in particular to a signalized intersection dynamic queuing length sensing and traffic signal control optimization algorithm, system and device based on vehicle-road cooperation. The signalized intersection dynamic queuing length sensing and traffic signal control optimization algorithm based on vehicle-road cooperation comprises the following steps: in a state of obtaining the current queuing length of each phase of an intersection, calculating the minimum green light time required for forming queuing vehicle emptying matched with the current queuing length of each phase of the intersection; forming an optimal green time ratio adjustment strategy in a state that the minimum green light time required for emptying the queuing vehicles is not matched with the current green light timing; and updating the current green light timing according to the optimal green time ratio adjustment strategy.

    本发明涉及智能交通关联技术领域,具体涉及一种基于车路协同的信号交叉口动态排队长度感知与交通信号控制优化算法、系统与装置。其中一种基于车路协同的信号交叉口动态排队长度感知与交通信号控制优化算法包括:于获取到路口各相位当前排队长度的状态下,计算形成与路口各相位当前排队长度匹配的排队车辆放空所需最小绿灯时间;于排队车辆放空所需最小绿灯时间不匹配当前绿灯配时的状态下形成最优绿信比调整策略;根据最优绿信比调整策略更新当前绿灯配时。
