Abstract

It is necessary to acquire information on traffic safety facilities installed on the roadways specifically for the operation of autonomous vehicles. The purpose of this study is to prepare a Korean version of an integrated message-set design as a way to provide to autonomous vehicles standardized information on traffic safety facilities. In this study, necessary facilities are classified according to four criteria (no legal basis; not providing information to autonomous vehicles; providing duplicate information; not standardized, and too difficult to generalize) based on information that must be provided to operate autonomous vehicles. The priority of information delivery (gross negligence followed by behavior change) was classified according to the importance of the information to be provided during autonomous driving, and the form was defined for the classification code in the information delivered. Finally, the information location and delivery method of traffic facilities for compliance with SAE J2735 were identified. This study is meaningful in that it provides a plan for roadway operations by suggesting a method for providing information to autonomously driven vehicles.

자율주행 자동차의 원활한 주행을 위해서는 도로상에 설치된 교통안전시설에 대한 정보 취득이 필요하다. 이에 본 연구는 자율주행 자동차에게 교통안전시설에 대한 표준화 된 정보를 제공하려는 방안으로 한국형 통합 메시지 셋 설계 방안을 마련하는 것을 목적으로 하였다. 연구에서는 자율주행 자동차의 주행을 위해 제공되어야 하는 정보에 따라 필요한 교통안전시설을 4가지 기준(법적 근거, 자율주행 자동차에 대한 정보 제공 유무, 중복된 정보 제공 유무, 기준 및 설치 형태의 모호성)에 따라 구분하였다. 주행 시 제공되는 정보의 중요도(12대 중과실, 행동 변화)에 따라 정보 전달의 우선순위를 구분하고, 전달 정보의 분류 코드 형태를 정의하였다. 마지막으로, SAE J2735 준용을 위한 교통안전시설의 정보 위치와 전달 방안을 파악하였다. 본 연구는 향후 자율주행 자동차의 실 도로 주행에 앞서, 일반 운전자 기준으로 설치된 교통안전시설이 자율주행 자동차에게 정보를 제공하는 방안을 제시함으로써 미래 도로의 운영 방안을 마련하였다는 데 의의가 있다.
