In order to reduce the time of model training and improve the possibility of large-scale deployment of signal lamp control, the invention provides a universal model system for signal lamp control, which comprises a feature extraction module and an action prediction module. Wherein the feature extraction module is used for converting traffic flow information of an intersection into an intersection information feature vector; wherein the traffic flow information comprises the average traffic flow under each traffic flow signal, the maximum occupancy rate of lanes within K seconds, the average occupancy rate, the movement direction, the number of lanes, the duration time of movement, whether the duration time is the minimum green light time or not, and whether the current signal is the green light or not. And the action prediction module is used for predicting the duration of the current signal lamp state of the intersection according to the intersection information feature vector. The current phase duration is set as the action, the concept of the traffic cycle is reserved, and the safety of traffic participants such as drivers and pedestrians is guaranteed.
为减少模型训练的时间,使提高信号灯控制的大规模部署落地的可能性,本发明提供一种用于信号灯控制的通用模型系统,包括特征提取模块以及动作预测模块。其中特征提取模块用于将交叉路口的交通流信息转换为路口信息特征向量,其中交通流信息包括各个交通流信号下的平均交通流量、K秒内的车道最大占用率、平均占用率、运动方向、包含车道数量、运动的持续时间、持续时间是否是最小绿灯时间、以及当前信号是否为绿灯。动作预测模块用于根据路口信息特征向量预测交叉路口的当前信号灯状态的持续时间。采用“设置当前相位持续时间”作为动作,不仅保留了交通周期的概念,也保障了驾驶员,行人等交通参与者的安全。
