Abstract

Korean society is rapidly changing to aging society comparing the other industrialized countries, however, the studies of elderly driver's driving behavior and accidents are not enough in Korea for elderly driver's accident prevention. This study focused on the elderly driver's psychological effects on elderly driver's driving behavior and traffic accidents; carefulness and aberrant driving behavior. - Elderly driver's traffic accidents The high percentage of elderly driver's accidents occurs in intersections and when turning left. There was a significant difference of the opponent vehicle's speed when left turn, between elderly driver and young driver; the elderly driver choose the higher speed of opponent vehicle than young driver when left turning. This result means that elderly driver has some problems with deciding the vehicle's speed and gap acceptance(Sunyeol Lee, Soonchul Lee, and Inseok Kim, 2006)(Table 1). - Carefulness and driving confidence In order to understand elderly driver's carefulness, this study compared the elderly driver's driving confidence. Driving confidence was consisted of 4 factors; environment of traffic condition, safe driving, driving ability and attention. Elderly driver's confidence was lower than young driver's. Elderly driver in high driving confidence group, showed longer driving history and they were tend to commit violations more frequently than elerly driver in low driving confidence group. Young driver, whose driving confidence level was high answered more driving history, annual mileage, the frequency of committing traffic violation and the experience of accident within lats 5 years(Soonchul Lee, Juseok Oh, Sunjin Park, Soonyeol Lee and Inseok Kim, 2006)(Table 2). This study examined the total time required until deciding to turn left in the no traffic signal intersection between elderly driver and young driver. The result showed that the time of elderly driver was significant longer than young driver(Sunyeol Lee et al, 2006)(Table 3). - Elderly driver's aberrant behavior Driver behavior Questionnaire(DBQ) was measured to understand the aberrant behavior; violation, error and lapse. The tend of aberrant behavior was observed by aging(Sunjin Park, Soonchul Lee, Jonghoi, Kim and Inseok Kim, 2006). Elderly driver's DBQ score was lower than young driver's(Table 4). Elderly and young driver showing longer driving history were in low DBQ score group. Elderly driver had high error score and young driver had high violation score. Young driver's aberrant driving behaviour was associated with annual mileage and the frequency of committing traffic violation. Elderly driver's aberrant driving behaviour was associated with annual mileage and experience of accident. Especially elderly driver whose violation, error and lapse score was high answered more committing experience of accident within last 5 years.

고령화가 다른 국가에 비해 상대적으로 빠르게 진행되고 있는 상황에 대비한 고령운전자의 연구가 부족한 실정이다. 본 연구는 고령운전자의 교통사고 원인을 신체적 능력저하보다도 심리적 요인의 변화에 입각하여 고찰해 보려고 한다. - 고령운전자의 교통사고 고령운전자의 교통사고에서 가장 두드러지게 나타나는 행동적 특징은 좌회전시 발생하는 교통사고가 많다는 것이다. 그리고 사고장소에 따른 분석결과에 의하면, 교차로에서 발생하는 사고가 많다는 것이 확인되었다. - 고령운전자의 조심성과 보상행동 고령운전자의 조심성이 운전행동에 미치는 알아보기 위하여 운전자의 운전확신수준을 비교해 보았다 운전확신수준은 4개 요인으로 구분되었고, 고령운전자와 젊은 운전자의 운전확신수준 차이를 검증한 결과를 보면, 고령운전자의 운전확신수준이 젊은 운전자에 비해 현저하게 떨어지는 것을 알 수 있었다 그리고 좌회전을 선택시 소요되는 시간을 분석하여 고령운전자의 조심성을 이해하려고 하였다 고령운전자는 젊은 운전자에 비해 선택소요시간이 현저하게 길어진다는 사실을 발견하였다. - 고령운전자의 운전일탈행동 연령에 따른 운전일탈행동의 변화를 보면, 연령이 증가함에 따라 운전일탈행동의 위반, 오류, 착오의 평균 점수는 감소하는데, 각 요인이 감소하는 정도는 차이가 있었다. 위반점수는 연령의 증가에 따라 급격하게 감소하는 모습을 보이는데 비해 오류와 착오점수는 연령의 증가에 따라 완만하게 감소하는 경향을 보였다.
