Analysis of resilience for urban transit networks

One of cornerstones for urban transit planning and public transportation management is topological properties of transit network. Through analyzing the real transit networks, the conclusion was gotten that transit networks are robust against random vertex removal but considerably less robust against targeted removal of the highest-degree vertices. “Betweenness centrality” of transit networks was used to explain the conclusion obtained. The research approaches of this article can be directly applied to determining the public transit hub and evaluating the performance of the whole transit network.
