The invention relates to a trunk line multi-lane afflux traffic signal control method, which comprises the following steps of S1, selecting a management and control road area, and extracting traffic data; s2, determining a bottleneck road section and a congestion influence range thereof based on historical traffic state data, and determining urban trunk system control subarea division in combination with node association degree; s3, OD path analysis is carried out on the vehicle; s4, a VISSIM simulation model is established; and S5, boundary control is carried out on the plurality of control subareas based on MFD, the total boundary adjustment amount is calculated with the maximum system income as the target, internal coordination control is carried out on the control subareas based on the SWARM optimization algorithm from the single point level and the coordination level at the same time, and a trunk line coordination control model is established. The method has the advantages that control is reasonable, and the traffic efficiency is improved.
本发明涉及一种干线多车道汇入交通信号控制方法,包括以下步骤:S1:选取管控道路区域,提取交通数据;S2:基于历史交通状态数据确定瓶颈路段及其拥堵影响范围,再结合节点关联度确定城市干线系统控制子区划分;S3:针对车辆进行OD路径分析;S4:建立VISSIM仿真模型;S5:基于MFD对多个控制子区进行边界控制,以系统收益最大为目标计算边界调节总量,从单点层面和协调层面同时考虑的基于SWARM优化算法的控制子区内部协调管控,建立干线协调管控模型,本发明具有合理管控、提升交通效率的优点。
