Three measuring methods for driving behavior were discussed. The first was to assess one’s own driving characteristics by using questionnaire, the DSQ. The second was the equipped vehicle to measure the driving behavior in the real road environment. With the vehicle, we have recorded the driving behavior, and individual difference when approaching to an intersection was investigated from the recoded data. We also have developed a driving simulator and analyze the individual difference in the visual behavior while turning at an intersection was investigated.
