유비쿼터스 레일시스템 적용기술 및 응용서비스분석

초록

As information technology has been rapidly developed, it is expected that the needs of ubiquitous for information on construction, maintenance and operational processes in railway field will arise. U-Rail system, for which information ubiquitous in railway field, can be defined as the human centered future railway system that enables to perform real-time state indication and auto information generation and its transmission by interchanging information organically among railway suppliers, users, and operator. In this paper, we analyzed main components of U-Rail system and its service items from the view of information technology and communication network technology, with focusing on railway field.
