The invention discloses a signal period dynamic regulation and control method for a staggered intersection in a vehicle-road coordination environment. The method comprises the following steps: 1, acquiring information of different types of vehicles on each lane at the t-th time interval of the staggered intersection; 2, determining an optimal signal period by using a signal period optimization model; 3, determining a staggered intersection management and control method according to road conditions; 4, determining an optimal signal timing scheme by using the optimal signal timing scheme model; and 5, circulating the steps according to the real-time change of the traffic flow at the intersection. According to the dynamic regulation and control method provided by the invention, the optimal signal timing scheme can be selected according to the real-time traffic volume and the dynamic regulation and control signal period, so that the vehicle delay is reduced, the vehicles can quickly pass through the staggered intersection, and the traffic operation efficiency of the staggered intersection is improved.

    本发明公开了一种车路协同环境下错位交叉口的信号周期动态调控方法,包括:1、采集错位交叉口第t个时间间隔下各车道不同类型车辆的信息;2、利用信号周期优化模型确定最佳信号周期;3、根据道路条件确定错位交叉口管控方法;4、利用最优信号配时方案模型确定最优信号配时方案;5、根据交叉口交通流实时变化,循环上述步骤。本发明提出的动态调控方法可以根据实时交通量,动态调控信号周期,选取最佳信号配时方案,减少车辆延误,使车辆快速通过错位交叉口,提高错位交叉口的交通运行效率。
