The invention relates to the technical field of road traffic signal control, and particularly discloses a traffic artery adaptive coordination control real-time iterative optimization method, which comprises the following steps: acquiring real-time traffic flow state and signal historical operation data of each intersection in a traffic artery; the method comprises the following steps of: iteratively calculating a current signal period interval of each intersection and an operation time interval of each signal phase in real time according to signal historical operation data of each intersection before the current signal period starts to operate; and each intersection in the interval runs the actual duration of each signal phase according to the respective real-time traffic flow state, so that independent self-adaptive control of each intersection under the traffic artery coordination control is realized. According to the invention, on the premise of ensuring the coordinated operation effect of the arterial traffic, each intersection in the arterial traffic can iteratively generate a matched signal control scheme in real time according to the dynamic change of the actual traffic flow, and the organic combination of the maximization of the control benefit of the single intersection and the maximization of the coordinated control benefit of the arterial traffic is realized.

    本发明涉及道路交通信号控制技术领域,具体公开了一种交通干线自适应协调控制实时迭代优化方法,包括:获取交通干线中各交叉口的实时交通流状态和信号历史运行数据;在当前信号周期开始运行前,根据每一交叉口的信号历史运行数据实时迭代计算出每一交叉口的当前信号周期区间和各信号相位运行时间区间;在此区间内每一交叉口根据各自的实时交通流状态运行各信号相位的实际时长,从而实现交通干线协调控制下每一交叉口独立的自适应控制。本发明能够在保障交通干线协调运行效果的前提下,做到交通干线中每个交叉口根据实际交通流量动态变化实时迭代生成匹配信号控制方案,实现单个交叉口控制效益的最大化和交通干线协调控制效益最大化的有机结合。
