The invention discloses a traffic signal timing optimization method for an urban updating area, belongs to the technical field of traffic optimization, and can solve the problem that the overall operation level of a road network of the urban updating area is poor due to the fact that the efficiency is low when a traditional traffic flow control method is used for processing traffic problems of the urban updating area. The method comprises the following steps: S1, determining the number of current running vehicles and the number of ideal running vehicles in a road network of the urban updating area according to traffic flow information of the urban updating area; s2, according to the traffic flow information, the number of current running vehicles and the number of ideal running vehicles, determining the traffic optimization duration of each boundary intersection road entering the interior from the periphery of the boundary line in the urban updating area; and S3, optimizing the initial traffic duration of each boundary intersection road by using the traffic optimization duration to obtain an optimized target traffic duration. The method is used for timing optimization of traffic signals in an urban updating area.
本发明公开了一种城市更新区交通信号配时优化方法,属于交通优化技术领域,能够解决传统交通流量控制方法在处理城市更新区交通问题时效率较低,导致城市更新区路网整体运行水平较差的问题。所述方法包括:S1、根据城市更新区的车流信息确定城市更新区路网的当前运行车辆数和理想运行车辆数;S2、根据车流信息、当前运行车辆数和理想运行车辆数,确定城市更新区中由其边界线外围进入内部的每个边界交叉口道路的通行优化时长;S3、利用通行优化时长对每个边界交叉口道路的初始通行时长进行优化,得到优化后的目标通行时长。本发明用于城市更新区交通信号的配时优化。
