Abstract

Currently, in our society with a substantial and increasing fraction of the elderly population, transport safety for elderly drivers is becoming the center of attention. However, deficient data on vehicle crashes in South Korea limits the growth of traffic accident research pertaining to the country. So, we complemented South Korean vehicle crash data by examining USA vehicle crash data, especially the data of Ohio State, and analyzing the influential factors of elderly driver-involved crashes of the State. Subsequently, we suggested a way of improving the South Korean dataset. Notably, our study showed that the influential factors were vehicle speed, posted speed, and following other vehicles too close and provided them in the South Korean dataset.

우리나라가 고령화시대에 진입하면서 고령운전자를 위한 교통 안전성 정책에 대한 관심이 높아지고 있다. 이를 위해서는 고령자 관련 교통사고의 영향요인을 분석하는 연구가 활성화될 필요가 있지만, 국내의 사고 데이터는 효과적인 사고분석 연구를 수행하기에는 한계가 있다. 이에 본 연구는 미국의 사고 데이터를 살펴보고 기계학습 알고리즘을 활용하여 고령운전자 사고심각도 예측 모형을 개발하고, 주요 사고 영향요인을 도출하여, 향후 국내 사고 데이터의 보완 방향을 제시하고자 한다. 분석 결과에 따르면, 주행속도, 제한속도, 사고 시 근접 주행 여부 등이 고령운전자 사고 심각도에 영향을 주는 요인으로 나타났는데, 한국의 사고 데이터에서 제공하지 않는 것으로 나타났다. 그러므로 이와 같은 정보들이 한국의 사고 데이터에서 제공된다면 고령운전자 교통안전성 제고에 기여할 수 있을 것이다.
