Functional reliability of tunnels and its impact on transportation network resilience (UTI-UTC 21)

This project explores how the functional reliability of tunnel systems influences the overall resilience of transportation networks during normal operations and disruptive events. By integrating operational data, structural performance metrics, and network modeling techniques, the research establishes a framework to assess the probability and consequences of tunnel functionality loss due to hazards such as structural failures, natural disasters, or extreme weather events. The project develops simulation tools to evaluate tunnel vulnerability within larger transportation systems and models cascading effects of tunnel outages on traffic flow, connectivity, and recovery timelines. Using case studies and real-world tunnel data, it identifies critical points of failure and proposes strategies for improving design, maintenance, and emergency response planning. The findings support infrastructure owners and public agencies in enhancing tunnel system resilience and ensuring network reliability in the face of growing risks.
