유비쿼터스 레일시스템 구현을 위한 주요 정보화 요소기술 분석

Analysis on the main information-based technology for realizing Ubiquitous Rail system

With the arrival of ubiquitous networking environment, it has been needed to build up the u-infrastructure for railway, and so the realization of ubiquitous rail system could be preferred. We have studied the direction for development of technology for realizing u-rail system through the analysis of the condition and demand on railway system, and investigated the requirements, level of technology and applicability of information infrastructure for realizing u-Rail. And also analyzed the technology based on railway information to determine the role of existing information system and connect it, which is adequate for u-Rail and the project selection.
