The Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) wrote this guide to help citizens understand how decisions are made at the local, State, and national levels, in the transportation planning process.

FTA and FHWA have initiated a series of joint Enhanced Planning Reviews (EPRs) to assess the impact of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) on the planning processes conducted by the transportation agencies serving metropolitan areas. The EPRs also are intended to determine the effects of planning on transportation investment processes. The EPR for the Washington, DC metropolitan area included federal site visits on December 12 and 13, 1994 and February 14 and 15, 1995. At the conclusion of the visit the federal team presented preliminary observations and recommendations to the local agencies taking part in the review. This final report describes the EPR in detail and provides summary conclusions as well as a complete set of observations and recommendations.

An integrated approach is presented for systematically incorporating social, economic, and environmental factors into transportation planning and decision making. The timely identification is stressed of the nature, magnitude, and incidence of these potential factors so that in all phases of transportation planning, alternatives may be developed that avoid or minimize adverse effects and that take full advantage of opportunities to increase benefits. The early, effective, knowledgeable involvement of the public to clarify issues and to aid in the development and evaluation of proposals in emphasized, and the effective use is stressed of expertise and resources both of the transportation agency and of other agencies with maximum flexibility and openess. Objectives for all phases of a transportation planning and design process are listed, a 4-phase study strategy is proposed, and the roles of the transportation professional are reviewed.
