Abstract: Definition of lane changing behavior,extract the driver lane changing data sequence from the real vehicle test data.Analyze test data of the different driver under the same road conditions,the results show that:there is small lateral acceleration in the lane change process,different drivers have different lane changing time,and lane changing time is the key feature reflects the driver individual characteristics,setting up lateral safety forewarning system adapting to different driving characteristics drivers can improve the practicability of driving assistant system.This study provides reference for control strategies meeting the driver characteristics and different safety requirements.

Key words: drivers vehicle test data, lane changing behavioral, the different driver, under the same road conditions
