The CMAQ Project Selection Process is incorporated into the affected Metropolitan Planning Organization’s (MPO) federally approved Planning Process. GDOT works with the nonattainment MPO to select projects that, at a minimum, meet the CMAQ requirements outlined in FHWA’s Interim Program Guidance document. GDOT and the MPO also weigh the merits and the benefits of the specific projects and how they fit into the MPO’s regional transportation and air quality planning. GDOT also allows the smaller nonattainment MPOs to build up their annual apportionments of CMAQ funding to fund larger projects, on a caseby‐ case basis. In the past, GDOT and the MPOs used a project
Cost Effectiveness Table and the project’s specific emissions reduction analysis to assist in selecting projects. The
Cost Effectiveness table was developed using Section 4. Project Analysis and Selection Practices that Support
Effectiveness of FHWA’s
SAFETEA‐LU Evaluation and Assessment Phase 1 document. The
Cost Effectiveness Table allowed us to normalize the cost of the projects and then rank the project by
cost effectiveness and air quality benefit. Moving forward, GDOT will continue to incorporate the CMAQ selection into the Planning Process and work with the MPOs to select projects that will have a positive impact on air quality and congestion. The positive impacts will be captured on future CMAQ Performance Management Measure Reports and the Annual CMAQ Reports submitted to FHWA.
In the Atlanta nonattainment area, GDOT works directly with the Atlanta Regional Commission (ARC) to administer the CMAQ project selection process. In coordination with GDOT, ARC has developed a competitive selection process with
Program Goals & Principles and Program Emphasis Areas that fit into the regions blueprint to meet the air quality and congestion reduction objectives. For more information on this process, please visit the
Atlanta Regional Commission Congestion Mitigation and Air Quality (CMAQ) Program.
In 2013, ARC developed a new emissions calculator that replaced the previous project air quality analysis tool. The new calculator requires a broader spectrum of inputs including detailed project information from planning partners, data from ARC’s travel demand model and MOVES emission rates. ARC’s calculator allowed the region the better standardize the project selection process.
