The safety of staff, customers and of general Public in general viewed as one of the most important requirements in the urban transit. The maintenance computerization system for car of urban transit is a part of standardization and development of urban transit system, and We have been performed the establishment of maintenance computerization system from 2001 to 2005. The RAMS (reliability, availability, maintainability and safety) estimation for maintenance computerization system are utilized in a variety of computerization system for user's convenience and safety in maintenance. Ever since its inception though, the urban transit has searched for ways to improve reliability, availability, maintainability and safety of the railway subsystem. Provision of a reliable maintenance system include RAMS of the vehicles plays a very important role in achieving a safe system.

Korea Rail Network Authority ordered Urban Transit Magrev System on the alternative tender lines. The project was contained order with GS Construction and Yooshin Corporation as a result of competition as 5 consortium. Urban Transit Magrev System route was constructed in the whole Yeongjong-dong and Yongyu-dong, Jung-gu, Inchen. The main project is via transportation center in Inchen Int'l airport ~ Work complex ~ Water park ~ Yongyu-station and has Total continuation of 6.1kilometers, Station of 6 spot, Car base of a spot, go out line(a single line) of 380meters. Scale of construction is Major of Roadbed, Railroad, Building, Inspection and Repair facilities. The first Urban Transit Magrev System in Korea is a new symbol of Korea and has polished beauty and creative artistry based on functional perfection. It was designed in harmony with Inchen Int'l Airport improving the dignity of SOC design.

Light rail transit is classified to rubber-tired LRT, lear induction motor LRT, steel wheel LRT, monorail and tramway. LRT except for tramway are usually operated without driver and tramway are driven depending on driver's sight like usual car. LRT, which is one type of urban guided transit, shall be operated according to domestic "Operational Regulation for Urban Guided Transit" but existing regulation does not contain the safety related codes for driverless operation. In this paper, we investigate "IEC 62267 : Railway Application-Safety Requirements for Automated Urban Guided Transit" and compensate for existing operational regulation by referring to international standard and operational rule of commercial line.

Urban rail transit offers target performance and function because various lower part system such as rolling-stock, signal, power and trackis consisted as complex. In order to function properly an urban rail transit which is complicated system to work as safety and reliability, System must secure safety with structure, design, manufacture, install and verification and it is important to establish a safety standard follows it procedures, establish what step all it is important to operate. Safety standard of urban transit infrastructure is minimum standard necessary to secure safety of signal, power and track. Urban rail transit standard business leads to make many requirements. Recently, many types of equipment have applied to manage requirements and standards for system efficiently in part of universal, airline and car accordingly applied equipments use to manage a pursuit(Trace) between standard of system. Especially importance of management is emphasized more become more. Importance of standard management which usesa computing support tool recently in transit filed is embossed and is predicted to be more such forward. Therefore we propose the effective method of management with infrastructure system by constructed data-base system.
