Abstract

In order to improve the operational management of urban railway systems during rainstorms and waterlogging events, this study employed the PSR model to establish a framework to analyze the vulnerability factors and to uncover the vulnerability formation mechanisms in the operational aspect of the urban rail transit system. The ISM-MICMAC model was subsequently used to analyze the hierarchy of influence among vulnerability factors and influence paths. The study classified the vulnerability of urban rail transit systems into five levels. It was found that the degree of greening around the station and the regional economic level are significant contributing factors to vulnerability, and two dominant influence paths have been discovered. Therefore, improving the regional economic level can enhance the transit system's resilience and increase the overall disaster prevention and relief capabilities in the face of heavy rainfall and waterlogging events.
