AASHTO MCTE-1, Managing Catastrophic Transportation Emergencies: A Guide for Transportation Executives (2015), is written for a chief executive appointed to lead a transportation organization. The guide notes that at some point during a tenure the executive will be called on to deal with a major emergency or disaster. Such events include floods, storms, fires, earthquakes, terror events, and other manmade or environmental incidents. It explains that the day-to-day methods used in normal operations will be insufficient to handle such an event. The guide acquaints the executive with the kinds of events that can occur and with the tools and people available, and it outlines the issues to consider when preparing for all-hazards emergency incidents. It is intended for transportation executives and the senior staff who support them.
