Evaluating Benefits from Transportation Investments Aligned with the Climate Action Plan for Transportation Infrastructure Phase II (Task Order 01)

Building upon two executive orders (EO N-19-19 and EO N-79-20) targeting the mitigation of greenhouse gas (GHG) emissions in California, the Climate Action Plan for Transportation Infrastructure (CAPTI) offers a comprehensive plan to work toward a more unified vision for transportation that prioritizes climate, health, and social equity. The purpose of this Task Order is to advance the assessment of statewide transportation investments under CAPTI by updating and applying a previously developed project-level Vehicle Miles Traveled (VMT) and emissions evaluation framework. This research will systematically review and revise VMT impact ratings for 152 infrastructure output types; apply the enhanced methodology to funding Cycle 4 and Cycle 5 of Senate Bill 1 (SB 1) programs; and evaluate how methodological updates affect prior-cycle estimates. The project will produce updated datasets, interim reports, a final report, and a public webinar summarizing findings. The goal is to provide Caltrans with a transparent, reproducible, and current VMT and emissions assessment framework that supports CAPTI implementation, improves investment decision-making, and enables consistent evaluation of transportation projects statewide. All tasks, deliverables, and analyses will be completed within the performance period of July 2026 through January 2028.
