Abstract
Metros are very popular in metropolises. Considering the undesirable interaction of different metro lines under emergency, a method for constructing the metro interaction network (MIN) is proposed. The Shanghai Metro interaction networks (SMINs) including the network currently in operation (SMINop) and its extension (SMINext) are analyzed. The results suggest that compared with SMINop, the efficiency of SMINext falls by 6.297%, but removing a vertex has less impact on its efficiency. SMINext performs better than SMINop in attack-based tests, with larger efficiency retention rates in degree-based attack and betweenness-based attack. Maintaining a high emergency handling ability is vital to the network operation of metros.
