The invention relates to artificial intelligence, and provides an intersection traffic signal control method and device and a storage medium; the method comprises the steps: determining a signal control object sub-region of a target intersection, and obtaining the basic data information of the signal control object sub-region; dividing a traffic flow change period of the signal control object subarea into at least two optimization time steps, and determining a queuing balance coefficient of the signal control object subarea in each optimization time step under the initial signal timing information; optimizing the initial signal timing information in each optimization time step of the signal control object sub-region according to the queuing balance coefficient to obtain optimal signal timing information in each optimization time step of the signal control object sub-region; and carrying out traffic signal control on the signal control object subarea based on the optimal signal timing information in each optimized step length time. According to the technical scheme provided by the invention, the problem of low traffic release efficiency of an existing traffic signal control method can be solved.

    本发明涉及人工智能,提供一种交叉路口交通信号控制方法、装置及存储介质,其中的方法包括:确定目标交叉路口的信号控制对象子区,并获取信号控制对象子区的基础数据信息;将信号控制对象子区的车流量变化周期划分为至少两个优化时间步长,并确定信号控制对象子区在初始信号配时信息下各优化时间步长内的排队均衡系数;根据排队均衡系数对信号控制对象子区的各优化时间步长内的初始信号配时信息进行优化,以得到信号控制对象子区的各优化时间步长内最优信号配时信息;基于各优化步长时间内的最优信号配时信息对信号控制对象子区进行交通信号控制。本发明提供的技术方案既能够解决现有交通信号控制方法交通放行效率低的问题。
