The invention is suitable for the technical field of intelligent traffic, and provides a traffic signal control method and control equipment, and the method comprises the steps: determining the first driving-out flow of each lane at the current moment through employing a traffic flow model based on the current traffic data and historical traffic data of each lane in a traffic region, the second driving-out flow of each lane at the current moment is determined through attention mechanism processing; determining the predicted driving-out flow of each lane at the current moment based on each first driving-out flow and each second driving-out flow; determining a predicted traffic state of each lane at a future moment based on a law of conservation of vehicles and each predicted driving-out flow; adjusting the passing duration of each lane based on a preset adjustment target and each predicted traffic state until a target passing duration conforming to the adjustment target is obtained; and controlling the passing duration of the traffic signal lamp of each lane to be each target passing duration. The accuracy of traffic signal control can be improved, so that the traffic efficiency of the traffic area is improved.
本申请适用于智能交通技术领域,提供了一种交通信号控制方法以及控制设备,包括:基于交通区域内每个车道的当前交通数据和历史交通数据,分别采用交通流模型确定各车道在当前时刻的第一驶出流量,以及通过注意力机制处理确定各车道在当前时刻的第二驶出流量;基于各第一驶出流量以及各第二驶出流量,确定各车道在当前时刻的预测驶出流量;基于车辆守恒定律以及各预测驶出流量,确定各车道在未来时刻的预测交通状态;基于预设的调整目标和各预测交通状态,调整各车道的通行时长,直至得到符合调整目标的目标通行时长;控制各车道的交通信号灯的通行时长为各目标通行时长。本申请能够提高交通信号控制的准确度,从而提高交通区域的通行效率。
