This paper constructs an evaluation system that reflects dangerous driving behavior. The evaluation system has a three-layer structure model of "Evaluation Index-Performance Mode-Driving behavior score." Verification of the feasibility of the model based on the relationship between the driver and the cause of the accident based on behavioral characteristics. First, the driving return survey data and accident form information of the real traffic accident cases of China In-Depth Accident Study (CIDAS) database are counted, and the character variables are converted into digital variables.
