The invention provides an urban road plane intersection signal timing optimization method, which comprises the following steps of: inputting road data into a central processing model to obtain classified arrangement data; inputting the classified data into an upper-layer road model to obtain a timing scheme; and inputting the classified arrangement data and the timing scheme into a lower-layer intersection model to obtain a current real-time phase switching decision. Through algorithm structure design of the upper-layer road model and the lower-layer intersection model, the traffic flow of the whole road and the traffic flow near the intersection are considered, and the optimal timing scheme is sought, so that the purposes of improving the road operation efficiency and relieving traffic congestion are achieved.
本发明提供了一种城市道路平面交叉口信号配时优化方法,包括如下步骤:将道路数据输入中央处理模型,获得分类整理数据;将所述分类整理数据输入上层道路模型,获得配时方案;将所述分类整理数据和所述配时方案输入下层交叉路口模型,获得当前实时的相位切换决策。本发明通过上层道路模型和下层交叉路口模型的算法结构设计,考虑整条道路的车流以及交叉口附近的车流,寻求最优化的配时方案,从而达到提升道路运行效率,缓解交通拥堵的目的。
