The resilience of a traffic network is critical for emergency relief in a public emergency. This paper evaluates the resilience of the high-speed railway network in the Yangtze River Delta based on the independent path. The dominance and vulnerability of nodes and edges are analyzed by node blockage and edge disruption simulation. The results show that the resilience of a node is basically consistent with the number of independent paths. Hangzhou, Nanjing, and Shanghai are the most dominant nodes. Their blockage will reduce the resilience of the traffic network by 55.02%, 48.41% and 41.86%, respectively. Meanwhile, their blockage will obviously reduce the resilience of vulnerable nodes such as Lianyungang and Huzhou. The most dominant edge is from Shanghai to Hangzhou, its disruption will reduce the network resilience by 26.18%. Hangzhou and Hefei, as cities with high dominance and high vulnerability, need to formulate contingency plans to reduce their vulnerability.
