A comprehensive road traffic Accident Index (AI) of two-lane highway intersection is established, using statistical value of traffic accidents. About 170 highway intersections are surveyed, accidents happened in recent four years at these intersections are collected, and AI of each intersection is calculated. The AI of the intersections is analyzed by the clustering statistical method and the critical value of each grade is generated. The results will provide reference to improving highway intersection safety, and help to optimize the allocation of resources.
