Performance-based Planning and Programming—Congestion Reduction and Air Quality Targets

Home » Our Work » Performance-based Planning and Programming

The Boston Region MPO envisions an equitable, pollution-free, and modern regional transportation system that gets people to their destinations safely, easily, and reliably, and that supports an inclusive, resilient, healthy, and economically vibrant Boston region.

-Destination 2050 Vision 

On October 20, 2022, the MPO board voted to adopt a set of updated performance targets pertaining to the Congestion Mitigation and Air Quality Improvement (CMAQ) program. These include targets related to non-single-occupancy travel,  person-hours of excessive delay, and emissions reductions from CMAQ-funded projects. These targets reflect two-year and four-year time horizons.  For more information about these CMAQ performance measures, targets, and related processes, please refer to the memorandum titled CMAQ Program Performance Targets-2022 (PDF) CMAQ Program Performance Targets-2022 (HTML)
