The key objective of this contract is to inform the California Air Resources Board on the quickly evolving transportation patterns resulting from the deployment and adoption of emerging transportation technologies, and the disruptions associated with the COVID-19 pandemic, and identify opportunities for reduction of vehicle miles travelled (VMT) and greenhouse gas (GHG) emissions from transportation.
This report focuses on the quickly evolving transportation patterns resulting from the adoption of ridehailing as part of the efforts accompanying the implementation of the Clean Miles Standard (CMS) regulation.
In the same efforts to understand the evolving travel-related activities and inform policymaking, the UC Davis 3 Revolutions Future Mobility Program conducted four waves of mobility surveys between Spring 2020 and Fall 2023. Key findings from the analysis of these data reveal that remote work and a combination of remote work and physical commuting (i.e., hybrid work) emerge as an enduring outcome of the pandemic.
This report reviews the available evidence on changes in household travel behavior resulting from the Covid-19 pandemic and provides an overview of potential state, regional, and local-level policies that could help to preserve changes that help to reduce VMT and reverse those that tend to increase VMT.
This research investigates these two crucial components of climate mitigation that have proven to be politically obstinate. Three studies will focus on the context in which land use and transportation policies are created – the "who, what, and why" of political influence – in order to better understand the barriers to and opportunities for policy change.
This report investigates how local governments (cities and counties) are implementing California’s Senate Bill 743, adopted in 2013 to eliminate traffic delay, measured using level-of-service (LOS) standards, as a basis for analyzing and mitigating transportation-related impacts of development projects and plans as called for under the California Environmental Quality Act (CEQA).

The goal of this study intends to understand the relative share of vehicle miles traveled (VMT) between a plug-in hybrid vehicle and a battery electric vehicle.
This paper examines mechanisms for autonomous vehicle-induced increases in vehicle miles traveled (VMT) – some of which are expected to have a disproportionately larger impact on rural VMT – and outlines five methods that have been used to study VMT changes: travel demand equalization; travel demand elasticity; travel demand models; and stated and revealed preference surveys.
This paper explores the presence and magnitude of potential co-benefits of reducing vehicle miles of travel, providing California-specific examples where available.
This white paper examines the co-benefits of reducing vehicles miles of travel. Examples include reductions in air pollutant emissions, water pollution, wildlife mortality, and traffic congestion, as well as improvements in safety and health, and savings in public and private costs.
