The nation’s critical infrastructure is aging and vulnerable to natural and man-made disasters. According to a national report in 2008, one of the 14 grand challenges for engineering in the 21st century is to restore and improve urban infrastructure including public transportation systems. To ensure that the public transit systems meet life-safety standards and other operational objectives, robust and resilient transit systems are needed.
In order to increase the resiliency of public transportation systems, we aim to identify and develop methods in terms of system robustness to provide a resilient transit system under the impact from different levels of natural hazards or other emergency situations.
To this end, we propose a performance-based engineering based approach to address the robustness in resilient transit systems by conducting vulnerability (static vulnerability is an antonym of robustness) analysis of transit systems under different hazard scenarios and determining optimal investment strategies and policies using a chance-constrained optimization formulation in response to different performance measure constraints.
