TPEG는 디지털방송 매체를 통해 교통 및 여행정보를 전송하는 표준 프로토콜로 이동환경에서 운전자들에게 실시간으로 교통정보를 제공할 수 있는 킬러 애플리케이션으로 기대를 모으고 있다. 교통정보를 데이터화해 지상파 DMB, DAB 등의 매체를 통해 이용자의 위치와 주변 정보를 실시간으로 전달하는 기술로 데이터의 부호화, 복호화 및 필터링 등 다양한 규격을 포함한다. TPEG는 DMB 등 휴대이동방송이 시작되면서 디지털 방송신호를 통해 개인 단말기에 멀티미디어 교통정보를 제공할 수 있어 최근 각광을 받고 있다. 본 고에서는 TPEG 서비스의 개요 및 개발현황, 사업자들의 TPEG 서비스 추진현황을 살펴보고, TPEG 서비스의 문제점 및 개선방안을 제시하고자 한다.
