Analyzing Railway Accidents Based on Complex Network and Cascading Failure

The increasing complexity in high-speed railway system is leading to potentially disastrous failure modes and new kinds of safety issues, which requires modern accident modeling approaches. In this paper, a new accident causation model is proposed for railway accident analysis based on the complex network and the cascading failure theory. The key causation factors and key causation factor chains that lead to the final accident are investigated, and the severity of the accident are evaluated based on the proposed accident causation network model. All these can support the government or associations with recommendations for accident prediction and prevention.
