摘　　要：基于美国I 880高速公路交通流数据,对由交通堵塞或事故诱发的二次交通事件的各项参数进行聚类分析并建立概率模型。运用这一模型可对I 880高速公路进行实时交通流监测,发现有安全隐患的路段并向控制中心发出警报,以减少交通事件的发生与相应的人员财产损失。On the basis of the traffic flow data of expressway 1 880 in U.S., parameters of secondary traffic incidents caused by traffic jams or traffic accidents were studied by cluster analysis and a probability model was established. This model is designed to applied in real-time traffic flow detecting in expressway 1 880 to find road sections with hidden dangerous and send warnings to the control center, so as to reduce traffic incidents and the corresponding property loss.
