A case study to assess the survivability of a large-scale urban intelligent transportation system (ITS) network is presented. The ITS for Boise, Idaho, was analyzed on the basis of two survivability assessment techniques, which are discussed and summarized. The first approach provides a qualitative assessment of the Boise ITS; it is based on the survivable systems analysis method as modified for critical infrastructure. The second approach provides a quantitative assessment of network survivability by using a multilayer graph-based approach consisting of the greater Boise area power grid and surface transportation system. The power grid and the physical and control transportation graphs were analyzed to determine the relative criticality of various network components. Macroscopic modeling was used to investigate the effect of components’ failure on the network’s operational characteristics. The greater Boise area has a population of more than half a million. The analysis presented here serves as a case study showing the means of assessing the importance of various components in critical infrastructure layers. The results have enabled traffic operators and decision makers in the Boise area to understand the effects of failure events and to prioritize threat mitigation alternatives.
