The invention discloses a driving risk assessment method and device based on driving behaviors. The method comprises the following steps: S1, acquiring parameter data and risk assessment indexes which influence the driving behaviors of a driver; s2, performing feature processing on the driving behavior parameter data of the driver in the step S1; s3, obtaining a logistic regression function; s4, establishing a driving risk assessment model; s5, performing model training on the driving risk assessment model based on a data set formed by the driver driving behavior parameter data after feature processing; and S6, performing driving behavior risk assessment based on the trained driving risk assessment model, and performing optimization suggestion on the driving behavior based on the importance parameters. According to the driving risk assessment method and device based on the driving behavior, the driving behavior of the driver and the risk caused by other surrounding environment factors to the fine-grained driving behavior can be comprehensively considered, the risk of the driving behavior of the driver is analyzed more finely, and optimization suggestions are given.
