Abstract

Wireless Access in Vehicular Environments (WAVE) communication technology, which provides vehicleto-vehicle and vehicle-to-infrastructure communication and offers safe and convenient service, has been developed for application to an Intelligent Transport System (ITS). This paper provides field test results on a study of the feasibility of WAVE technology application to railway communication systems. A test railway communication system based on WAVE technology has been built along the Daebul line and a newly developed EMU. Field tests have been carried out according to the communication function requirements for LTE - R. The test results show that the railway communication system based on WAVE technology meets the functional requirements: maximum transmission length is 730m, maximum transfer delay is 5.69ms, and maximum interruption time is 1.36s; other tests including throughput test, video data transmission test, VoIP data test, and channel switching test also produced results that meets the functional requirements. These results suggest that WAVE technology can be applied to the railway communication system, enabling Vehicle-to-Wayside communication.

차량무선통신(WAVE)은 고속이동환경에서 차량간 통신(V2V), 차량과 인프라간 통신(V2I)을 가능하게 하고 안전 및 편의 서비스를 제공하는 무선통신기술로써 지능형 교통시스템(ITS)에 적용을 위한 연구가 진행되고 있다. 본 논문에서는 WAVE 통신기술을 철도분야에 적용하기 위하여, 철도시험선에 WAVE 통신 기반의 시험용 무선통신시스템을 구축하고 현차시험을 수행하여 철도전용 통합무선망(LTE-R)의 통신성능 요구사항 충족 여부를 검토하였다. 시험 결과, 최대전송거리는 730m, 평균전송지연은 최대 5.69ms, 단절시간은 최대 1.36s로서 목표 요구사항을 충족하였으며, Throughput 및 영상데이터 전송, VoIP 데이터 전송, 채널 스위칭 시험도 성공적으로 수행되었다. 이상의 시험결과로 부터, WAVE 통신 기술이 철도분야에 적용 가능하다는 것을 확인하였으며, 차-지상간의 안정적인 무선통신시스템 구축을 가능하게 할 것으로 기대된다.
