Modeling Urban Surface Transportation Network Dependability and Security

As transportation systems continue to be stressed by increasing traffic needs, they have incorporated intricate networks to optimally signalize intersections and gather information in real time. Such "intelligent" transportation systems (ITS) require extensive interaction with other critical infrastructures such as communications and power. Rapid incremental design of these systems has focused almost exclusively on safety and efficiency while typically downplaying the equally important need of survivability. Supporting infrastructures are improvised to meet transportation needs while ignoring survivable design. As a result, the delicate interaction of these systems is often compromised at multiple single points of failure, resulting in frequent failures of one infrastructure that profoundly affect others. The reluctance in system designers of accounting for survivability is understandable--it is costly to incorporate redundant designs as back up components provide deminishing returns on continued maintenance of the system. Therefore, when seeking to improve system survivability, an effort must be made to identify those components that would benefit most--components that are both essential to the needs of the system, and vulnerable enough to justify the cost of design improvements or redundant backups. The University of Idaho's National Institute for Advanced Transportation Technology (NIATT), in conjunction with the Idaho Transportation Department (ITD) and other stakeholders, has initiated an analysis of the Moscow ITS for potential improvements. One research focus is examining the survivability of the system, analyzing potential improvements and determining how similar approaches can be applied to other ITS's and critical infrastructures throughout the nation.
