4.2 Areas for Federal Policy Action Federal policies are needed in five general areas: 1) research; 2) transportation planning processes; 3) project development/NEPA; 4) design and engineering considerations; and 5) specific programs and funding. These recommendations are summarized below, and identified as short- or medium- to longer-term recommendations. Short-term recommendations are those that should be implemented immediately and are the logical first steps in improving the resilience of our nation’s transportation system; specific policy mechanisms for doing so are discussed in
