摘要

This paper presents a modified topological vulnerability analysis for the metro network. The flow impacts and the capacity constraint are taken into account in this work. A node-based congestion is considered in the travel time model for the metro network. The logit-based path choice model is adopted to assign the flow in the network. Based on the present approach, the efficiencies of the metro network with either fully or partly damaged stations can be analyzed. The vulnerability of the Beijing metro network was studied based on the present method. The results show that the flow in the network plays an important role in the vulnerability analysis. Topological methods neglecting either the flow or the flow impacts would underestimate the vulnerability of the network. Both the magnitudes and patterns of origin-destination (O-D) demand influence on the assessment of vulnerabilities of the metro network and on the importance ranking of stations. Additionally, in a busy metro network the vulnerability would distinctly relate to the percentage of passengers who continue to choose the metro as a means of transportation after a disaster. On the contrary, such responses of travelers have no significant influence in a free metro network. (C) 2016 American Society of Civil Engineers.
