Surface Transportation: Clear Federal Role and Criteria Based Selection Process Could Improve Three National and Regional Infrastructure Programs

摘要

To help meet increasing transportation demands, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) created three programs to invest federal funds in national and regional transportation infrastructure. As requested, this report provides (1) an overview of the goals, funding status, and types of projects and activities funded by the three programs; (2) advantages and challenges identified by program stakeholders; and (3) potential program enhancements. GAO reviewed pertinent federal laws and rules; examined plans for selected projects; conducted site visits; and interviewed officials, stakeholders, and experts. The goals of the projects funded by the three national and regional infrastructure programs--Projects of Regional and National Significance (PNRS), the National Corridor Infrastructure Improvement Program (NCIIP), and the Coordinated Border Infrastructure (CBI) program--are varied, most projects have been reviewed and funded, most projects are for highway improvements, and funds have been applied toward various related activities. PNRS and NCIIP funds were distributed by congressional directive, and CBI funds were distributed by formula.
