Early Warning Methodology for Urban Rail Transit Operation Safety: Empirical Study from Guomao Station, Beijing

With the development of urban mass transit, the metro system has become the backbone of urban transport and attracted a large scale of passengers, which tremendously affect the security, efficiency and service level. Therefore, the early warning of metro stations is the key to safety insurance. In this study, we took Guomao Station as the empirical study, calibrated the threshold value, established the warning index system and proposed some measures to guarantee the operation in Guomao Station and verified the feasibility and practicability of the early warning methodology.
