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.

1. INTRODUCTION

Transit network is an important research object in transportation engineering. After intensive study, various approaches of transit network planning were proposed and many metrics for evaluating the network properties were formed. With the development of computer and complex network sciences, the basis on which the mechanics of network's evolution and complex status can be researched is fixed.
