Abstract

Urban subway systems are confronted with various factors, including man-made or natural disasters, that will lead to service disruption. In recent years, as the consequence of subway failure is barely affordable, the vulnerability analysis of metro system has become popular in studies. This paper proposes to measure the differences of vulnerability caused by different route planning choices. In this paper, a directed and weighted network based on passenger flow is reconstructed with the metrics that represent the paths’ and network’s attributes. The definition of network vulnerability is put forward and applied in the case study of Washington DC’s subway. Through the analysis for the vulnerability of the network with four different new routes added separately, the results show that the decrement of vulnerability varies severely with different route planning choices. The results of this paper indicate the necessity of considering network vulnerability as an important factor in subway route planning.
