Research to Assess Potential Synergistic Emissions Benefits

Project Information

Project ID:
FHWA-PROJ-19-0067
Project Abstract:

This report examines the potential for synergistic emissions benefits for groups of projects funded by the congestion mitigation and air quality Improvement (CMAQ) program. The key issue being addressed is the extent to which multiple projects might have synergistic effects—i.e., the benefits of the whole set of projects being greater than the sum of the benefits of individual projects. The report provides information to support State and metropolitan planning organization (MPO) investment and policy decisions involving multiple factors affecting transportation-related outcomes; may be of value to State Departments of Transportation (DOT) and MPOs interested in conducting programmatic assessments of the set of CMAQ projects under review; and lays a framework for testing suites of CMAQ projects for evaluating their combined or synergistic effects towards improving air quality and relieving congestion. The report describes benefits, challenges, and solutions in leveraging potential synergies among CMAQ projects. It provides grouping scenarios and sample menus of projects that might be expected to create synergies, for both metropolitan and statewide levels of application.

Project Outcomes/Impact:

The objectives of this research are to assess potential for synergistic emissions benefits for grouped projects funded by the CMAQ Program. This research will provide tools and information using project combination scenarios to support State and MPO investment and policy decisions involving multiple factors affecting transportation-related outcomes. This research may also serve to inform the application of 23 USC 149(j) which allows for optional programmatic eligibility for CMAQ projects.
