Abstract

Autonomous Vehicles(AV) are considered as an alternative to solve various social problems. Many researches which are related to developing technologies and AV operations have been conducted vastly and on-going. However, there seem to be little studies on various influences of AI algorithm on driving installed in AV. This study aims to examine the impacts of the ethical decisions made by Utilitarianism-based AI in AV when the oncoming car crossed over the central line. It establishes scenarios about situation of encroaching a central line and analyzes traffic impacts of ethical decision made by AV. According to the results of the analyses, as th accident occurs, overall speed of traffic decrease. There is a negative impact on the traffic flow when AV made an Utilitarian-based ethical decision by changing the lane. However, when AV choose to collide head-on, there is a positive effect to relieve traffic flow with an assistance of CACC, equipped.

자율주행차량은 다양한 사회 문제를 해결하기 위한 대안으로 각광받고 있다. 자율주행차량의 도입 및 관련 기술 개발 연구가 활발히 진행되고 있으나 자율주행차량에 탑재된 운행 알고리즘에 따른 실제 운행의 영향력에 대한 연구는 미흡한 실정이다. 본 연구에서는 한정된 물리적 환경에서 공리주의와 사회적 합의를 고려하여 차량 운행 중 발생 가능한 상황인 중앙선 침범 상황에 대한 시나리오를 설정하고 시뮬레이션을 통해 윤리적 판단이 필요한 상황에서의 자율주행차량의 운행에 따른 영향을 분석하였다. 분석 결과, 자율주행차량이 안전도를 판단하여 옆 차선으로 차선을 변경한 시나리오에서 사고에 따른 영향이 더 큰 것으로 나타났다. 또한 자율주행차량의 판단에 따라 전방 충돌한 경우, 자율주행차량의 기능에 의해 교통류 개선 효과가 있음을 확인하였다.
