Projects

This research will address policy-relevant questions by investigating cost-efficient ways to implement a RUC, evaluating the equity impacts of RUC, and quantifying factors that influence household’s PEV adoption decisions.

This dissertation will present an evaluation framework, using material from California as a case study, to prioritize the adoption of SCM by concurrently considering (1) material performance, (2) resource availability, and (3) environmental impact reduction.

This project explores the probability of developing a centrally coordinated routing system for trucks. The project develops a method for estimating the utility functions of truck drivers based on their response to a centrally coordinated routing system that they are participating, and it also evaluates the impact of assumed wrong utility functions that could be viewed as non-compliance on the system optimum cost.

This project addresses the need to increase access to grant funds to develop electric vehicle (EV) carsharing in underserved communities, particularly in rural and suburban areas. The research team designed this translational research project to engage communities interested in developing electric carsharing programs.

The project addresses and discusses environmentally effective ways to deal with greenhouse gas, a harmful byproduct of cement production. It considers the necessity of using Direct Air Capture technology to minimize greenhouse gas (GHG) emissions (reaching net-zero GHG emissions is a regulatory mandate for the State of California’s cement industry).

This project will investigate how and whether localities are able to effectively integrate use of both level-of-service (LOS) and vehicle miles traveled (VMT), identify the best practices, and provide recommendations for Caltrans and other state agencies for assisting localities.

This research focuses on transportation of underserved people in the Sacramento area of California and aims to explore their barriers to and facilitators of adoption of a technology-enabled on-demand service—microtransit—and how and to what extent it helps get access to services and employment by employing quantitative methods based on data collected through phone and intercept surveys.

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. 

Policymaker and technical decision-makers currently do not have clear and consistent methods for identifying and prioritizing what new approaches to use. The white paper will concisely summarize a framework and practical steps for reviewing and comparing policies and technical decisions regarding pavement.

The project will help centralize and assess evacuation routes, and assess their capacity for evacuation. It will help inform infrastructure investment priority decisions, as it will identify the road segments with the largest impact on the evacuation route/network performance.

In this project, the research team will quantify the magnitude of micromobility service effects on vehicle miles of travel (VMT) through triangulation and synthesis of three primary travel behaviors: mode substitution, transit connection, and driving/ride-hailing behavior.

This project will produce a Talent Pipeline Blueprint report that identifies the necessary steps required to build cross-campus CSU talent pipelines that target the most in-demand trade and transportation occupations requiring specific degrees, certificates, and non-credit professional development.

This research will expand on EVALUATE, Phase I by testing the tools developed in that project in an urban area, developing guidance to assist others in using these tools in other regions, and performing technology transfer activities to get the tools in the hands of practitioners and decision makers.
