The invention discloses a highway interlacing area traffic accident prediction method, which comprises the following steps of: selecting a highway interlacing area as a research object, establishing an incidence relation among road geometric design, traffic flow and interlacing area accident risk by utilizing a Logistic hierarchical regression model, and establishing an accident risk model. By quantitatively analyzing the influence of the road geometric design on the accident risk, the traffic accident risk of the interlaced area is effectively and accurately predicted.

    本发明公开了一种高速公路交织区交通事故预测方法,该方法选择高速公路交织区作为研究对象,利用Logistic分层回归模型,建立道路几何设计、交通流与交织区事故风险的关联关系,建立事故风险模型。本发明通过定量分析道路几何设计对事故风险的影响,有效、准确地预测交织区交通事故风险。
