The invention discloses an urban area road traffic coordination control method based on road network subarea division, which comprises the following steps: setting a period duration for detecting a congestion state of an urban area road, and acquiring traffic data of the urban area road according to the period duration; the method comprises the following steps: acquiring traffic data of primary urban region roads, and performing road network sub-region division on the traffic data to obtain k road network sub-regions; according to the traffic data of each road network sub-region, determining the traffic congestion level of the road network sub-region; constructing a function model with multiple objective functions and multiple constraint conditions for the road network subareas; and an initial coordination control scheme is generated for the k road network subareas in sequence to form an urban area road traffic coordination control scheme of the current round. According to the method, the internal congestion traffic flow can be dispersed in the area as much as possible and evacuated out of the area, the purpose of avoiding or delaying urban area road traffic congestion is achieved, and the relieving effect is better than that of timing control and coordination control without road network subarea division.
本发明公开了一种基于路网子区划分的城市区域道路交通协调控制方法,包括设置检测城市区域道路拥堵状态的周期时长,按周期时长获取城市区域道路的交通数据;获取一次城市区域道路的交通数据,对其进行路网子区划分,得到k个路网子区;根据每个路网子区的交通数据,确定其交通拥堵等级;对路网子区,构建多目标函数多约束条件的函数模型;并依次对k个路网子区生成初始协调控制方案,构成本轮的城市区域道路交通协调控制方案。本发明能尽可能地将内部的拥堵交通流在区域内进行分散,以及向区域外进行疏散,达到避免或者延缓城市区域道路交通拥堵发生的目的,缓解效果优于定时控制和不进行路网子区划分的协调控制。
