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.
