Abstract

Based on a review of interagency consultation processes from across the Nation, the FHWA has compiled successful examples of State and local agencies and their efforts to improve the transportation conformity process. A total of 34 States have been included in this review, and successful examples are outlined in table format within the report. Findings of this report suggest that interagency consultation, if performed early in the metropolitan planning process, may assist State and local decisionmaking at the regional level. The establishment of emissions budgets through the Statewide Implementation Plan (SIP) process needs to include the transportation sector to ensure that future conformity issues are not raised at the last minute during metropolitan planning and transportation improvement program development and updates.
