Improving Access and Efficiency to Transportation Affordable Programs in California

Principal Investigator Caroline Rodier, Ph.D.
University of California, Davis

This project addresses the Caltrans research need as outlined in the 2022-2023 UC Davis Caltrans Research Grants: "Existing assistance programs often function as discretionary rather than entitlement programs. These programs are first-come, first-serve, and often over-subscribed. They tend to use limited dollars to channel large benefits to relatively few beneficiaries, leave many eligible households unassisted, and are rarely evaluated." The researchers will use a three-part approach to identify near and longer-term opportunities to provide more effective UBM programs.
