Abstract

Next-generation ITS(Intelligent Transportation System) adopts WAVE(Wireless Access in Vehicular Environment) system which is capable of the bidirectional communication system in vehicular environments. u-Transportation system adopted WAVE communications system to show the optimal performance in terms of various services with regard to vehicle safety and traffic. In this paper, we introduce testbed of ubiquitous-Transportation system and its service. Then, we describe WAVE system for supporting next-generation ITS service. Also, we carried out tests in real road environments in order to verify communication functions of WAVE systems and its performance. We confirmed that our communication systems for supporting services meet the communication performance.

차세대 ITS 시스템은 고속 이동환경에서 양방향 통신이 가능한 WAVE 시스템을 적용한다. u-Transportation 시스템은 차세대 ITS 시스템의 하나로 다양한 차량 안전 및 교통서비스 제공에 최적화된 성능을 보여주기 위해 WAVE 시스템을 적용한다. 본 논문에서는 u-Transportation 시스템 테스트베드와 이를 위한 서비스에 대하여 소개하고, 차세대 ITS 서비스 지원을 위하여 구현한 WAVE 통신시스템에 대해 설명한다. 구축한 테스트베드를 통하여 실제 도로 환경에서 차세대 ITS 서비스를 지원하기 위한 통신 기능 및 성능 시험을 수행하였다. 자동차 전용도로 및 도심 도로 구간에서의 서비스 시험 및 운영을 통해, 서비스 제공에 필요한 통신시스템의 기능과 차량 이동환경에서 통신 성능을 만족하는 것을 확인하였다.
