abstract="For rail transit systems, safety is one of the most important goals that need to be guaranteed. We build a method of railway system safety analysis based on the cusp  catastrophe model. This method describes the continuous changing process of railway  system safety and considers the emergent property of safety. This method solves the  problem that the outputs of most static analysis methods of railway system safety do  not have continuity and avoids the complex analysis process and heavy computation  burden brought by using some dynamic models such as state transition models. The  quantitative case study of the continuous changing process of system safety in the  evolution process of the Yong-Wen railway accident shows that the visualized outputs  obtained by using this method are consistent with the actual situation. This method  has the potential to be applied in the real-time monitoring of railway system safety  and the early warning of train accidents.<p /> <p>Language: en</p>",
