Title:

Measuring Vulnerability of Urban Metro Network from Line Operation Perspective

Abstract:

Urban metro systems are subject to recurring service disruptions for various reasons, including mechanical or electrical failures, adverse weather or other accidents. Studies on metro networks attract increasing attention in recent years because the consequence of operation accidents is unaffordable. This paper proposes to measure metro network vulnerability from the perspective of line operation by taking Shanghai Metro Network a case study. Different from previous studies focusing largely on dysfunction of important nodes or links, this study investigates the disruption from line operation perspective. Betweenness centrality, number of missed trips, weighted average path length and weighted global efficiency were analyzed for each line of disruption using the field passenger flow data. Passenger flow distribution and re-distribution were simulated for different scenarios by following an all-or-nothing assignment principle. Network topological properties were investigated for baseline and disruption scenarios. Results indicate that metro lines carrying large number of passengers generally have a significant impact on the network vulnerability, further demonstrating the importance of the circular line for both network topology and passenger transfer as it generally offers more alternative routes. Findings of this study could provide suggestions on metro system administration for potential improvement on the performance of operation and passengers may meanwhile have an improved alternative plan for their commuter trip.
