• Abstract:
  Management of critical transportation assets such as bridges and tunnels has traditionally focused on condition preservation through carefully planned life-cycle activities within a budgetary limit. Although there are calls to consider various risks from extreme events, existing approaches to risk assessment in transportation asset management rely heavily on engineering judgement and past experience. This subjective and empirical approach to risk assessment contrasts to more objective methods that are underpinned by quantitative models of hazards, vulnerabilities, and consequences. Nonetheless, these quantitative models do not fully consider the effects of deterioration on structural vulnerability under extreme events, thus hindering their direct application in transportation asset management. The primary goal of this research is to facilitate risk-based transportation asset management using (a) objective and consistent risk assessment and (b) performance risk analysis for large-scale transportation networks. Three major tasks were conducted: (a) establish the general framework for objective risk assessment of deteriorating assets; (b) achieve objective agency risk assessment in transportation asset management systems; (c) develop effective and efficient methods for network-level performance risk assessment.
