The invention relates to the technical field of intelligent traffic, and discloses a real-time traffic signal control method, system and device based on road network coordination. The infrastructure parameter set of the to-be-controlled road network, the preset model basic parameter set, the first operation data set of each operation vehicle in the to-be-controlled road network and the second operation data set of each to-be-operated vehicle are acquired in real time through the preset decision time interval, and then the traffic flow characteristics of the to-be-controlled road network can be determined in real time through the data. Furthermore, a corresponding mathematical optimization model is established through the obtained traffic flow characteristics in combination with a preset model basic parameter set and a signal display state set, and the signal display state of each flow direction in the road network to be controlled in a prediction time range can be controlled by solving the model. Therefore, by implementing the method, the coordination between adjacent intersections and a plurality of intersections and a plurality of different paths in a road network can be realized, and the requirements of sufficiently facing the future environment and moderately advanced technical development are met.

    本发明涉及智能交通技术领域,公开了一种基于路网协调的实时交通信号控制方法、系统及装置,本发明通过预设决策时间间隔实时获取待控制路网的基础设施参数集、预设模型基本参数集和待控制路网内各运行车辆的第一运行数据集和各待运行车辆的第二运行数据集,进而通过上述数据可以实时确定待控制路网的交通流特征。进一步,通过得到的交通流特征并结合预设模型基本参数集和信号显示状态集建立对应的数学优化模型,并通过求解该模型可以实现待控制路网内每个流向在预测时间范围内的信号显示状态的控制。因此,通过实施本发明,可以实现相邻交叉口之间以至路网内多个交叉口、多个不同路径的协调,满足了充分面向未来环境且适度超前的技术发展需要。
