The invention discloses a user driving behavior analysis method and system. The method includes: collecting vehicle driving data of several users, and calculating several index items used to describe the user's driving behavior according to the vehicle driving data; obtaining traffic accident information of the user; using the index items as characteristic variables, analyzing the relationship between each characteristic variable and the The correlation of traffic accident information, screen out N characteristic variables with the highest correlation with the traffic accident information, and form an N-dimensional vector; use nonlinear dimensionality reduction algorithm to reduce the dimension to obtain a variable set; take the variable set as an independent variable, and use The traffic accident information is used as a dependent variable, and a user driving behavior evaluation model is trained; the user driving behavior evaluation model is used to evaluate the driving behavior of the user to be analyzed. The invention uses the traffic accident information as a quantitative index for evaluating the user's driving behavior, trains the user's driving behavior evaluation model, and improves the prediction and evaluation accuracy of the user's driving behavior. |
