The invention discloses an intelligent traffic signal control method and system based on vehicle-road cooperation, and belongs to the technical field of traffic control, and the method specifically comprises the steps: setting the initial time length of a collection period as T when the initial vehicle flow in the driving direction is in a set interval [M, N]; every acquisition period T, the system obtains traffic flow Q in all driving directions of the intersection and generates a traffic flow sequence; calculating the mean value of the traffic flow in all the driving directions every m acquisition periods, and dynamically adjusting the green light signal time distribution in each direction in unit time according to the traffic flow proportion in different driving directions; meanwhile, analyzing the proportions q and t which exceed and are lower than the interval value in the sequence and the linear fitting slope k after the scatter diagram is generated, and calculating the adjustment coefficient beta of the collection period according to the proportions q and t; according to the method, the traffic flow collection period is dynamically adjusted, so that the method adapts to the actual traffic flow change, and the traffic management efficiency is improved.

    本发明公开了基于车路协同的智能交通信号控制方法及系统,属于交通控制技术领域,具体包括:当行车方向内的初始车流量位于设定区间[M,N]内时,采集周期的初始时长设为T;每隔采集周期T,系统获取路口所有行车方向的车流量Q,并生成车流量序列;每隔m个采集周期,计算所有行车方向的车流量均值,并根据不同行车方向的车流量比例动态调整单位时间内各方向的绿灯信号时间分配;同时,分析序列中超过和低于区间值的比例q和t,以及生成散点图后的线性拟合斜率k,据此计算采集周期的调整系数β;该系数用于动态调整接下来的采集周期时长T’=T/β;本发明通过动态调整车流量采集周期,适应实际车流量变化,提高交通管理效率。
