The invention provides a man-vehicle-road coupled driving risk prediction method and system. The method comprises the following steps: S1, analyzing risk characteristics of a vehicle following scene and a lane changing scene; s2, constructing a driving risk assessment method based on man-vehicle-road coupling, analyzing driving collision points, and predicting an uncertain risk area; and S3, constructing a driving safety early warning system based on an uncertainty risk analysis result. Accurate evaluation, prediction and early warning of the driving risk situation are realized, and a foundation is laid for improving the driving safety and reducing the driving accident rate.

    本发明提供了一种人车路耦合的行车风险预测方法及系统,包括:步骤S1:分析跟车场景、换道场景的风险特征;步骤S2:构建人车路耦合的行车风险评估方法,并分析行车碰撞点,预测不确定性风险区域;步骤S3:基于不确定性风险分析结果,构建行车安全预警系统。本发明实现了行车风险态势的准确评估、预测、预警,为提高行车安全性、降低行车事故率奠定基础。
