Abstract

C-ITS(Cooperative-Intelligent Transportation System) provides services that require strict real-time such as forward collision warning, road safety service and emergency stop. WAVE(Wireless Access in Vehicular Environments), a core technology of C-ITS, is a technology designed for high-speed driving. However, in order to provide stable communication service by applying to real road environment, various performance tests of real vehicular environment are required. In the real road environment, WAVE communication performance is influenced by the surrounding environment such as moving vehicle, road shape and topography. Especially, when the vehicle is moving at high speed, the traveling position according to the speed of the vehicle, The surrounding environment changes rapidly. Such changes are factors affecting the communication performance, therefore a system and methods for analyzing them are needed. In this paper, we propose the configuration and test method of an effective performance evaluation system under high-speed driving and describe the results of analyzing the communication performance based on the data measured through the actual vehicle test.

C-ITS(Cooperative-Intelligent Transportation System)는 전방 충돌 경고, 도로 안전 서비스 및 비상 정지와 같은 엄격한 실시간성이 요구되는 서비스들을 제공한다. C-ITS의 핵심 기술인 WAVE(Wireless Access in Vehicular Environments)는 고속 이동 환경을 위해 고안된 기술이지만, 실제 도로 환경에 적용하여 안정적인 통신 서비스를 제공하기 위해서는 실차 환경의 다양한 성능 시험이 요구된다. 실제 도로 환경에서 WAVE 통신 성능은 이동 중인 차량, 도로의 형상 및 지형 등의 주변 환경에 의해 영향을 받으며 특히, 차량이 고속으로 이동하는 경우 차량의 속도에 따라 주행하는 위치와 노변장치와의 접근성 등 주변 환경이 빠르게 변화한다. 이 변화는 통신 성능에 영향을 주는 요소이므로 이를 분석하기 위한 시스템과 방법이 필요하다. 본 논문에서는 고속 주행 환경에서 효과적인 성능 시험 시스템 구성과 시험 방법을 제안하고, 실차 시험을 통해 측정한 데이터를 기반으로 통신 성능을 분석한 결과를 제시한다.
