A transportation problem in Korea is a serious issue that has to be solved urgently in the motor era of 15 million vehicles. Recently ITS has been introduced to improve efficiency of the current roads because an excessive budget and a long term construction are needed to build new roads. Therefore the government enacted the law as of ITS and the in architecture. However, these ITS information services were oriented to mainly vehicles and drivers, not public entities such as bus driver, passengers and so on. Nowadays lots of local autonomous city introduced a public transportation information system (PTIS), and providing useful information for the public. For this PTIS, important design issues are to be focused on detecting and tracking technology of moving bus, and a wireless communication link to transmit the location information. This paper presents design models using several wireless communication methods, and an implementation case using a Wireless packet Data communication Network (WDN) to transmit bus location information at Seoul, Korea.

교통 환경 개선을 위해 지능형교통시스템을 도입하여 지자체의 발전을 가속화 시키고 있다. 지난번에 3개의 시를 첨단교통모델도시로 선정하여 ITS의 교두보를 마련하여, 현재 9개의 도시에 u-City구축을 위해 추진하고 있어 각 도시의 개발사업현황을 알아보았다. 본 논문은 지능형교통체계 구축사업 분석과 특징, VISION, 국가 ITS사업을 위한 효율적인 추진전략을 제시하고 발전 방안을 연구하였다.
