The invention relates to an intersection short-time signal state pre-pushing method and system based on intelligent network connection vehicle group perception, and the method comprises the steps: collecting the state of a traffic signal lamp based on the intelligent network connection vehicle group perception data, inputting the state of the traffic signal lamp into a pre-pushing model, and carrying out the recognition of a signal control scheme of a single intersection; pre-pushing a signal state of a single intersection; and pre-pushing the signal states of the plurality of intersections in a combined manner. And a subsequent short-time traffic signal state is predicted and deduced in a self-adaptive manner through a machine learning method. According to the method, different prediction and inference processes are respectively given for a single intersection independent control mode and a multi-intersection cooperative control mode, and the method is applicable to various scenes. And a reliable short-time traffic signal state data basis is provided for planning and decision-making of an intelligent network connection vehicle group.

    本发明涉及一种基于智能网联车群感知的交叉口短时信号状态预推方法及系统,所述信号状态预推方法基于智能网联车群感知数据的采集交通信号灯状态,将交通信号灯状态输入预推模型,包括单个交叉口信号控制方案辨识;单个交叉口信号状态预推;多个交叉口信号状态联合预推。通过机器学习方法自适应预测推断后续的短时交通信号状态。本发明针对单个交叉口独立控制和多个交叉口协同控制两种模式,分别给出了不同的预测推断流程,适用场景多样。为智能网联车群的规划与决策提供了可靠的短时交通信号状态数据基础。
