The Digest’s 2025 Multi-Slide Guide to National Impacts of Community-Level Strategies to Decarbonize and Improve Convenience of Mobility

This project links the POLARIS, GTT, and TEMPO national modeling tools to assess the national impacts of community-level, convenience-focused decarbonization strategies. This strategic connection extends high-fidelity regional analysis to the nationwide county level. The resulting quantitative insights help communities optimize investments in highly-ranked strategies like Land Use and Travel Demand Management. This informs multi-objective decisions to improve equitable mobility and reduce transportation emissions nationally, supporting the U.S. Decarbonization Blueprint.
