Robustness of transportation networks subject to degradable links
University of Massachusetts - Amherst, MA 01003, USA
Accepted: 17 October 2007
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.
