This study explores factors contributing to the decrease in biking and walking in California over the period from 2012 to 2017, as observed in comparisons of the most recent California Household Travel Survey (CHTS) and the California add-on sample of the National Household Travel Survey (NHTS), respectively.
This project aims to understand current federal road funding, with the aim of facilitating a transition between a traditional fuel tax and a road charge mechanism.
This white paper discusses a potential "Vehicle Miles Traveled (VMT) Peak" for the 21st century. It presents a research agenda designed to clarify the reasons for the current VMT peak and to assess the implications for future passenger travel demand in the U.S.
Using Anna’s hummingbird as a case study, the researchers propose to develop a genetic toolkit to assess how Caltrans construction projects impact bird populations.
This study focuses on combining road charges (mileage-based fees) with pricing strategies to meet affordability, equity, congestion, and emissions goals.
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.
