In this paper, we demonstrate how to capture the robustness of a transportation network in the case of degradable links represented by decreasing capacities. The analysis is conducted by utilizing Bureau of Public Road link travel cost functions and a recently proposed network efficiency measure for congested networks. For specific networks we are able to derive lower bounds for the robustness when percentage reductions in the link capacities take place.
