AASHTO HAZ-1, Fundamental Capabilities of Effective All-Hazards Infrastructure Protection, Resilience, and Emergency Management for State Departments of Transportation, was published in September 2015. The guide grew out of AASHTO and Transportation Research Board work on security management that followed the events of September 11, extending lessons learned to all forms of threats to the transportation system. It sets out a set of fundamental capabilities that state departments of transportation can apply to infrastructure protection, resilience, and emergency management. The document reflects rising customer expectations for system performance and reliability and lower tolerance for delays, under which even small events can have magnified impacts. It also responds to an evolving hazard environment that includes extreme weather and cyber incidents alongside traditional threats. State DOT staff responsible for security, resilience, and emergency management programs can use the guide as a reference.
