On constructing and utilizing database for Korean Urban Rail Transit standardization project

A variety of Urban Rail Transit (URT) systems have been operating in Korea and they have different technology bases, causing a lot of difficulties in taking measures against trouble, training, upgrading, interoperability and so on. As such, a standardization project has been carried out to solve the problems by setting up the national standards for the systems. The main role of the project is to support the governments, the operation companies and the industries according to the URT law, and also the law itself. A common database was built using a systems engineering tool to provide the integrated engineering environment to the community of URT project. This paper discusses the design of the database and how it can be utilized in the successful promotion of the project. The products of the projects are stored into the database to be referred to by other new projects for reusing sharing the information. A key usage of the database is obtained by managing the traceability among the products and regulations through cross organizations. The traceability will provide a strong basis for any new development of systems that need to consider the products of previous projects, standards and regulations perspectives. Also, the incorporation of the newly coming and ever changing standards or regulations is possible for the development using the traceability among the changes in them.
