Abstract
Subway system is associated with a high level of uncertainty because it usually operates in a dynamic environment in which technical and human and organizational malfunctions may cause possible accidents. This paper proposed a Bayesian network approach to model causal relationships among risk factors. This model explicitly represented cause and effect assumptions between variables. The method allows for multiple forms of information to be used to quantify model relationships, including formally assessed expert opinions whe quantitative data are lacking. This makes the risk and safety analysis of subway systems more functional and easier. A case study of the fire risk due to human errors during operation was used to illustrate the application of the proposed model.
