Betweenness Centrality is not a Network Resilience Metric

Betweenness centrality measures the importance of a link or node in a network based on how often it falls on the shortest path between other nodes. It was originally introduced in social network analysis, where it is interpreted as the ability an actor has to moderate communication between others in the network. In transportation, it is often used as a measure of the resilience impact of a particular link. In this article, I argue that betweenness centrality is not a theoretically valid measure of resilience, and provide hypothetical networks where it clearly fails to identify resilience issues.
