Congestion Mitigation Air Quality
The Congestion Mitigation Air Quality (CMAQ) program is one source of funds for Transportation Control Measures (TCMs) employed for the purposes of reducing congestion and improving air quality.
MAP-21, the Moving Ahead for Progress in the 21st Century Act (P.L. 112-141), was signed into law by President Obama on July 6, 2012, containing several changes to the CMAQ program. The Fixing America’s Surface Transportation Act (FAST) Act was signed into law on December 4, 2105 expanding on the MAP-21 CMAQ program as described on FHWA’s FAST ACT CMAQ website.
CMAQ Improvement Program can be found at the Federal Highway Administration. The FHWA also provides a summary of the CMAQ Program on their YouTube page.
