DEVELOPMENT OF A DRIVING STYLE FEEDBACK METHOD AIMED AT ADAPTIVE LEARNING IN SAFE DRIVING EDUCATION

The aging of driver's license holders is progressing, and in order to allow elderly people to continue driving safely, license renewal periods have been shortened and license systems have been introduced that allow elderly people to drive only vehicles equipped with specific safety devices.In human factors research, it has been pointed out that the driving characteristics of elderly people are caused by a decline in cognitive function due to aging as well as a decline in judgment function, which leads to accidents.Research and development of technologies such as low driver alertness and inattentive detection is being conducted.However, it has not yet been possible to extract critical variables that lead to unsafe behavior in elderly people, which varies greatly from person to person.This research focuses on risk communication using hazard maps as a support measure to help them break away from highly unsafe driving behavior.Drivers have misconceptions about driving, habits that have become habitual through driving experience, and unconscious behaviors that belong to psychomotor skills.This study aims to develop a feedback method to link drivers' self-understanding of their driving style with the risks associated with that style.As a preliminary survey, the driving style (8 factors) of 624 men and women aged 70 or older was analyzed to compare with the driving style of 320 men and women aged 40 to 60 who have elderly drivers in their close friends, and significant differences were found in several factors.Based on the analysis results, hazard map training was conducted after presenting the self-diagnosis results of driving style to 27 drivers aged 70 or older, and a change in awareness of hazards was observed.
