The purpose of this study is to explore ways of improving the motor vehicles safety certification system in preparation for the deployment of Lv.4 or higher autonomous vehicles. In order to effectively achieve the objectives of this study, theoretical and empirical research methodologies were employed, including literature review of prior research, government-published data, etc.; comparative research on legislative cases of other countries regarding motor vehicles safety certification; historical and legal research on domestic systems; legal analysis to explore approaches for improvement, etc. Some argue that the type approval system is needed in preparation for deploying autonomous vehicles, but there are several limitations in moving to the type approval system from the self-certification system currently adopted in Korea. First, there is a possibility that the system may be in conflict with the Korea-U.S. MOU regarding Foreign Motor Vehicles (1988) and the Korea-U.S. FTA (2011); second, there is a risk of undermining the cause of the self-certification system, which is the autonomy of manufacturers; third, the boundary between autonomous vehicles and non-autonomous vehicles is unclear; and fourth, the type approval system may hinder technological competitiveness. On the other hand, considering that the Korea-U.S. FTA and the UNECE IWVTA recognize exceptions to deal with road safety and risks to human health or the environment, and have a pre-certification system for some auto parts such as pressure-resistant containers, it can be said that there is room to introduce the type approval system for supplementation purposes. To improve the motor vehicles safety certification system while ensuring the safety of autonomous vehicles of Lv.4 or higher, the targets of type approval should be defined and the criteria, procedures, etc. for type approval should be established. At the same time, the consistency between motor vehicle-related laws and harmonization with international standards need to be considered.

도심 항공 모빌리티(Urban Air Mobility, UAM)의 핵심 이동수단인 개인 항공기(PAV) 및 화물 운송용 무인항공기(Cargo UAS)는 항공기 시스템의 설계 적합성과 안전성을 동시에 확보해야 한다. 이를 입증하여 형식 증명(인증)을 받으려면 안전성 분석 및 평가를 항공기 개발과정 초기부터 전체 주기에 걸쳐서 체계적으로 수행해야한다. 그러나 안전 필수 항공시스템의 복잡도가 증가하고 최첨단 시스템이 적용됨에 따라 기존의 경험기반, 절차기반의 안전성평가만으로는 항공기 시스템의 안전성을 객관적으로 평하기 어려워졌다. 이러한 문제를 해결하기 위해 국내외적으로 모델링 및 시뮬레이션 기술을 이용한 모델기반 안전성평가(Model-based Safety Assessment, MBSA)가 활발히 연구되고 있다. 본 논문에서는 비행 시뮬레이터와 타겟의 시뮬레이션 모델을 연동한 통합 비행 시뮬레이터를 활용한 모델기반 안전성평가 프레임워크를 제안하였다. 공중충돌방지시스템(Traffic Collision Avoidance System, TCAS) 과 휠 제동 시스템 (Wheel Brake System, WBS) 사례연구를 통해 제안된 프레임워크를 UAM 안전성평가에 적용 가능함을 확인하였다.
