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.

Incentive Systems for New Mobility Services

Research Product Type

Research Report

With rapid population growth and urban development, traffic congestion has become an inescapable issue in large metropolitan regions. This research project studies the problem of offering incentives to organizations to change the behavior of their individual drivers (or individuals using their organization’s services).

Incentive Systems for New Mobility Services to Reduce Congestion

Research Product Type

Research Brief

Researchers at the University of Southern California developed a distributed algorithm for offering incentives to organizations to make socially optimal routing decisions designed to lower the traffic flow of congested roads without creating new congestion in other parts of the road network.

Intelligent Transportation Systems for Improving Traffic Energy Efficiency and Reducing GHG from Roadways

Research Product Type

Policy Brief

This policy brief discusses the benefits of Intelligent Transportation Systems (ITS), which have generated considerable enthusiasm in the transportation community due to their potential for improving roadway safety, reducing traffic congestion, and enhancing the mobility of people and goods.

Longitudinal Analysis of COVID-19 Impacts on Mobility: An Early Snapshot of the Emerging Changes in Travel Behavior

Research Product Type

Associated Publication

This study evaluates the impacts of the pandemic on mobility by analyzing micro panel data. The panel makes it possible to observe initial trends in travel behavior change, adoption of online shopping, active travel, and use of shared mobility services.

Mobility Justice in Rural California: Examining Transportation Barriers and Adaptations in Carless Households

Research Product Type

Research Report

This report describes the scope and scale of car access in rural areas, identifies barriers that rural zero-car and car-deficit households face in their mobility and access, and proposes personal and policy-level adaptations that would help these households achieve their mobility and access needs using descriptive analysis from US census microdata and interviews with 22 residents of California’s Central Valley.

New mobility service users' perceptions on electric vehicle adoption

Research Product Type

Associated Publication

Researchers explore the users of the new mobility services and their relation to electric vehicles preferences by analyzing two large-scale mobility service surveys.
