The invention provides a driver behavior data analysis method and system. The driver behavior data analysis method comprises the steps of obtaining speed values of a plurality of continuous discrete time points in driving record data; wherein the driver behavior data comprises driving record data; obtaining speed values corresponding to multiple types of roads through discrete Fourier transform; and comparing the standard feature vector according to the current driver behavior feature vector obtained by analyzing each acquisition point to obtain driver warning information. According to the method, the behaviors of the driver can be integrally assessed, the behavior data such as speed change characteristics of different drivers are obtained through multi-point collection of the driving speed of the driver and discrete Fourier transform, the accuracy of predicting the behavior data of the driver is improved, dangerous driving behaviors can be effectively predicted, and driving safety isguaranteed.
