차세대 지능형 교통 시스템(C-ITS) 및 자율주행의 핵심 기술인 V2X는 자동차와 외부 환경 간의 원활한 연결을 가능하게 하는통신 기술이다. 본 논문에서는 V2X 통신 기술을 표준, 서비스 및 특성에 따라 분류하고, 단일한 통신 방식 선택에 대한 국내외 동향을 알아본다. 그리고 현재 상용화가 가능한 C-V2X 기술 중 하나인 LTE-V2X(Rel.14)를 활용하여 LoS환경에서 RSU와 OBU 간통신 시 V2X 통신영역, 패킷 전송 지연시간, 패킷 수신 성공률을 측정한다. 이를 통해 LTE-V2X 기반으로 Day-1 C-ITS 서비스를효과적으로 적용할 수 있음을 확인하였다.
Abstract
V2X, which is a key technology for C-ITS and autonomous driving, is a communication technology that enablesseamless connectivity between vehicles and their surroundings. This paper classifies V2X communicationtechnology based on standards, services, and features, and reviews both domestic and international trends in theselection of a single communication method. Furthermore, we tested the communication range, data transmissionlatency, and PER during communication between the RSU and OBU in a LoS environment using one of thecommercially available LTE-V2X (Rel. 14) technologies. The results confirmed that Day-1 C-ITS services can beeffectively applied based on LTE-V2X.
