Congestion Mitigation and Air Quality Improvement Program

OMB 2125-0614

Section 1808 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users calls for an Evaluation and Assessment of CMAQ projects. The statute calls for the identification and analysis of a representative sample of CMAQ projects and the establishment and maintenance of an automated database that describes the impacts of the program both on traffic congestion levels and regional air quality. Given the CMAQ program's direct focus on mobile source emissions reduction and traffic congestion mitigation, this collection effort is tied to DOT Strategic Goals in Mobility and the Human and Natural Environment
