The Structure of Standard Specification and Safety Standard of Urban Transit’s Signaling System in Korea

摘要

Railway signaling system is the core technology to secure safety and punctuality. The system in Korea is currently applied to each railway organization with a differently and independently developed form handed from various signaling systems of other countries. The problem from the above reason makes the identification time of the causes of failure and the maintenance time longer, makes the quality of the railway operation, the service quality for the general public degraded, makes relevant matters to its interoperability, operation, maintenance, and training difficult even for the same functions, and thus, results in excessively expensive expenses. To make a preparation for the continuous expansion of the urban transit lines, and the improvement of the existing urban transit ones, the advanced standardization of signaling systems, which is following the current technological trend, is required. As the demands of the improvement of our own technologies and the security of compatibility among different products, studies on establishing standard specifications and safety standards are conducted. In this paper the structure of the standard specification and the safety criterion are represented.
