FHWA Office of Natural Environment - Congestion Mitigation and Air Quality Improvement Program
The Air Quality and Noise Abatement Team administers air quality and noise programs designed to lessen the impacts of transportation related noise and exhaust emissions. The CMAQ Program provides support for transportation programs and projects that reduce air pollution in EPA designated non-attainment and maintenance areas. Assistance and guidance is provided to MPOs, DOTs and other transportation related planning organizations in the development of Transportation Conformity Demonstrations to minimize the air quality impacts of changes to the transportation network. Noise Abatement or the most effective control of highway traffic noise requires a three part approach: Noise Compatible Planning, Source Control and Highway Project Noise Mitigation.
