Measuring Robustness and Coverage of Transportation Networks with Multiple Routes and Hubs

Robustness, or the resilience of a system to failures and attacks without changing its mode operation, is an increasingly important characteristic networks. Even though there are several measures network robustness, they not applicable networks with links between same pair nodes (multiline networks), such as transportation systems. A local index set global indexes introduced capture robustness having multiple connections nodes. These new designed uncover potential vulnerabilities components (i.e., hubs, terminals, lines) possible malfunctions that might be well identified traditional connectivity matrix–based methods.
