최근 주변 사물에 부착된 센서를 이용하여 실시간 수집된 센싱정보를 무선 네트워크를 통하여 제공하는 USN(Ubiquitous Sensor Network) 기술에 대한 국내의 관심이 급증하고 있다. 이미 선진국에서는 USN 기술이 기존의 IT산업뿐만 아니라 교통, 환경, 유통, 물류 등의 산업 전 분야에 활용이 가능하다고 판단하고, 다양한 응용 기술개발 및 시범사업을 추진해 오고 있다. 현재 국내에서도 정통부와 건교부를 중심으로 USN 기술을 안전운전 서비스 및 교통정보 수집체계 구축에 적용하기 위한 기술개발과 시범사업이 추진되고 있다. 본 고에서는 향후 USN 기술의 Killer Application으로 성장 가능한 서비스로 도로환경에 설치된 센서노드를 이용하여 차량 및 도로정보를 실시간 수집하고, 이들 정보를 활용하는 차세대 텔레매틱스 서비스의 기술개발 방향에 대하여 자세히 논하고자 한다.
