초록

자율주행자동차로 인해 기존의 교통사고 원인의 대부분을 차지하는 '운전자부주의'로 인한 교통사고가 크게 감소할 수 있지만, '트롤리 딜레마', 차량 결함, 도로 함몰 등과 같은 사고를 피할 수 없는 상황이 발생할 수 있다. 이 경우 사람과 같은 윤리적 선택이 필요해진다. 본 연구는 돌발적인 싱크홀이 발생하여 자율주행차가 교통사고를 피할 수 없는 상황을 가정하고, 자율주행자동차의 윤리적 선택에 따른 교통사고비용을 시뮬레이션 분석을 통해 추정하였다. 이 때 자율주행자동차는 (1) 탑승자의 안전을 최우선으로 하는 이기주의, (2) 인명피해를 최소화하는 의무론, (3) 사고비용을 최소화하는 공리주의의 3가지 윤리적 선택 중 한 가지를 선택하도록 하였다. 분석결과, 이기주의의 교통사고비용이 가장 높게 분석되었고, 인명피해를 최우선으로 하는 의무론의 교통사고비용이 가장 낮게 분석되었다.

Autonomous vehicles can significantly reduce accidents due to 'driver's carelessness', which occupies the majority of causes for traffic accidents, but they may fail to avoid traffic accidents due to unexpected situations, such as "trolley dilemma", vehicle defects and road defects. Therefore in situations Autonomous vehicles need to be made ethical choices. This study assumes that Autonomous vehicles can not avoid traffic accidents due to unexpected sink holes. In this situation, the traffic accident costs was analyzed for the ethical choices of Autonomous vehicles. In the process, Autonomous vehicles were made to choose one of three ethical choices : (1) Egoism with priority on passenger safety, (2) Deontology for minimizing human damages, (3) Utilitarianism with minimizing traffic accident costs. As a result of the analysis, egoism had the highest traffic accident costs, and deontology for minimizing human damages had the lowest traffic accident costs.
