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.

Transportation Control Measures

Under the Transportation Conformity Rule, Transportation Control Measures (TCMs) are strategies that are specifically identified and committed to in State Implementation Plans (SIPs), and are either listed in Section 108 of the Clean Air Act (CAA) or will reduce transportation-related emissions by reducing vehicle use or improving traffic flow.
