Identifying, Assessing, and Managing Events for Critical Infrastructure Resilience in Surface Transportation

State departments of transportation (DOTs) play an important role in protecting critical transportation infrastructure from natural hazards, human-caused events, and emerging threats. However, there is currently no consistent methodology for identifying and assessing critical infrastructure within surface transportation systems. Definitions of “criticality” vary across agencies, and existing approaches often lack integration with broader resilience, security, and emergency management frameworks. Previous research has focused on specific threats, such as terrorism or cybersecurity, or on resilience to natural hazards, but gaps remain in developing proactive, risk-based approaches that address the full range of threats and system interdependencies. Transportation systems are closely linked with other infrastructure sectors, such as power and water systems, and disruptions can have cascading impacts across regions. Research is needed to help state DOTs better define their role in coordinating with law enforcement, emergency responders, and other planning partners and system owners to enhance preparedness, response capabilities, proactive resilience planning, stakeholder coordination, and implementation of national infrastructure protection frameworks. The objectives of this research are to (1) identify and assess surface transportation system interdependencies and develop a risk-based approach to managing a wide range of threats; and (2) develop an infrastructure resilience guide with case studies, a list of stakeholder roles and responsibilities, and decision-making tools to help state DOTs identify, assess, and manage risks to critical infrastructure within surface transportation systems.
