The invention relates to a signal intersection traffic accident risk real-time prediction method based on a conflict extreme value. The method comprises the following steps: step 1, collecting traffic conflict index data; step 2, constructing a conflict extreme value distribution model; and step 3, constructing an accident risk evaluation index to obtain a real-time prediction result. According to the invention, in the vehicle-road cooperation environment, the moving trajectory of the road user can be rapidly and accurately obtained, the time-space diagram of each signal period is drawn, and technical support is provided for real-time prediction of the traffic accident risk of the signalized intersection in the vehicle-road cooperation environment.

    本发明涉及本发明一种基于冲突极值的信号交叉口交通事故风险实时预测方法,包括以下步骤:步骤一、收集交通冲突指标数据;步骤二、构建冲突极值分布模型;步骤三、构建事故风险评价指标,得到实时预测结果。本发明在车路协同环境下,可以快速而精确的获得道路使用者的运行轨迹、绘制每个信号周期的时间‑空间图,为车路协同环境下信号交叉口交通事故风险的实时预测提供了技术支撑。
