本发明实施例提供一种区域路网交通信号灯协调控制系统和装置,该系统包括云端中心,以及设置于区域内每一交叉口的边缘节点和多源交通数据采集设备,所述边缘节点一端连接对应交叉口的多源交通数据采集设备,另一端连接所述云端中心,临近边缘计算节点之间相互连接。本发明设立智能化的独立边缘节点,利用边缘节点的计算能力处理多源交通数据,感知交通运行状态。多个边缘节点与云端中心联合动作,采用多智能体强化学习方法协调优化区域内各个交叉口的交通信号灯配时方案。可以有效的解决城市交通拥堵问题,提高交叉口机动车通行效率。

    The embodiment of the invention provides a regional road network traffic signal lamp coordination control system and device. The system comprises a cloud center, edge nodes and multi-source traffic data acquisition equipment, the edge nodes and the multi-source traffic data acquisition equipment are arranged at each intersection in an area, one end of each edge node is connected with the multi-source traffic data acquisition equipment of the corresponding intersection, the other end of each edge node is connected with the cloud center, and the adjacent edge computing nodes are connected with each other. According to the invention, the intelligent independent edge nodes are set, the multi-source traffic data is processed by using the computing power of the edge nodes, and the traffic operation state is sensed. A plurality of edge nodes and a cloud center act jointly, and a multi-agent reinforcement learning method is adopted to coordinate and optimize a traffic signal lamp timing schemeof each intersection in an area. The problem of urban traffic jam can be effectively solved, and the motor vehicle passing efficiency at the intersection is improved.
