The invention relates to the technical field of road traffic safety, and discloses a road interleaving area traffic safety state prediction method comprising the following steps: S1, obtaining ramp information of an interleaving area, and installing a traffic detection device on a road section of the interleaving area; s2, collecting traffic flow information of an interlaced area through the traffic detection equipment installed in the S1, and performing research and analysis through historical accident data of the area; s3, analyzing the historical accident data in the S2, and counting the time sample of each piece of accident data to obtain an accident sample of the road section; through the method, the spatial-temporal characteristics of the traffic flow data can be automatically extracted, the integrity of the data is ensured, information loss is avoided, the risk prediction model is established by using the data information through the method, and collision risk dynamic prediction is realized, so that a worker can adjust the state of the traffic flow in real time according to a prediction result, and the traffic flow prediction efficiency is improved. And the traffic operation safety is improved.

    本发明涉及公路交通安全技术领域,且公开了一种公路交织区交通安全状态预测方法,包括以下步骤:S1:获取交织区的匝道信息,在交织区的的路段上安装交通检测设备;S2:通过S1中安装的交通检测设备进行对交织区的车流信息进行收集,并通过该区域的历史事故数据进行研究分析;S3:针对S2中的历史事故数据进行分析,并对每条事故数据的时间样本进行统计,得的该路段的事故样本;通过该方法,可以对交通流数据进行自动提取时空特征,确保了数据的完整性,避免了信息丢失,通过该方法,利用数据信息,进行建立风险预测模型,并实现碰撞风险动态预测,使得工作人员可以根据预测结果实时对交通流的状态进行调节,提高交通运行安全。
