The invention relates to an intersection motor-non-motor vehicle conflict severity safety early warning method. According to the early warning method, the intersection motor vehicle and non-motor vehicle traffic is taken as a key feature, correlation between the intersection motor vehicle and non-motor vehicle traffic and intersection safety is constructed, a real-time monitoring system of intersection motor vehicle and non-motor vehicle conflict severity is obtained, and the system is used for safety early warning and is convenient for traffic police departments to reasonably arrange police strength. The safety early warning method comprises the following five steps of: 1, acquiring characteristic data; 2, building and training an intersection motor-non-motor conflict severity prediction model based on fuzzy clustering analysis and a BP neural network; and step 3, evaluating and predicting the severity of the motor-non-motor conflict at the intersection in real time. And 4, transmitting the output severity level of the motor-non-motor conflict at the intersection to an upper computer of a traffic police team command center through 5G. And 5, the traffic police team timely arranges proper police strength and formulates a reasonable scheme according to the obtained vehicle and non-vehicle conflict severity level of the current intersection.

    本发明涉及一种交叉口机非冲突严重度安全预警方法;所述预警方法以交叉口机非流量为关键特征,构建其与交叉口安全的相关性,得到交叉口机非冲突严重度的实时监测系统,用于安全预警,方便交警部门合理安排警力。所述的安全预警方法包括5个步骤:步骤1:采集特征数据。步骤2:搭建并训练基于模糊聚类分析和BP神经网络的交叉口机非冲突严重度预测模型。步骤3:实时评估和预测交叉口机非冲突严重度。步骤4:将输出的交叉口机非冲突严重度等级通过5G传输给交警队指挥中心的上位机。步骤5:交警队根据获得的当前交叉口的机非冲突严重度等级及时安排适当警力和制定合理方案。
