초록

DSRC 교통정보시스템은 노변기지국과 차량에 장착된 하이패스 단말기와의 통신을 이용한 구간 검지기로서 도로 교통정보를 수집하여 운전자에게 신뢰성 높은 교통정보를 제공하고 있다. 이에 국토교통부는 DSRC 교통정보시스템을 ITS 성능평가 대상으로 고시하였으며, 전국고속도로, 국도 및 지자체에 설치된 DSRC 교통정보시스템에 대한 성능평가를 실시하고 있다. 현재 DSRC 교통정보시스템은 장비 이상에 따른 고장수리 및 제어기부에 대한 상태확인 등 단순점검 위주로 관리되고 있어 노변기지국의 통신영역, 안테나 방향, 전파세기 등에 관한 세부적인 운영·유지관리 기준이 필요하다. 본 연구는 노변기지국별 상이하게 운영되었던 DSRC 교통정보시스템에 대한 최적의 품질관리기준을 마련하는 것에 목적이 있다. 품질관리 기준안으로 노변기지국의 통신영역 및 통신출력을 포함하고 안테나의 방향, 설치 높이, 각도 등 물리적인 설치 기준과 다양한 도로 유형별, 환경별 설치 지침을 제시하였다. 제시한 품질관리 기준안은 이동식 DSRC 기지국을 이용하여 설치 기준의 타당성을 검증하였다.

A dedicated short-range communications (DSRC) traffic information system is a detection system for a section of road using communication between roadside equipment and on-board High-Pass units to collect road traffic information and provide reliable traffic information to drivers. The Ministry of Land, Infrastructure, and Transport announced that a DSRC system must be supported to pass the performance evaluation of an intelligent transportation system (ITS), and the performance evaluation for DSRC systems installed in expressways and national highways is started. Currently, DSRC traffic information systems are only managed for maintenance and functional-monitoring purposes, which means that detailed criteria for the operation of a DSRC traffic information system, such as communication range, the direction of the antenna, and the power of the radio wave, etc., need to be established. In this paper, the criteria of the performance evaluation of a DSRC traffic information system are presented for different road types and road environments. The proposed performance evaluation criteria included the communication range and communication power of roadside equipment. In addition, installation criteria, such as the direction of the antenna, and the height and angle of the installed system, are presented for different road types and road environments. The criteria presented were evaluated for DSRC roadside equipment and documented to improve system maintenance and quality control of the communication system.
