Policy Brief

Researchers at the University of California, Davis and the non-profit organization Mobility Development reviewed evaluations of the travel, emissions, and equity effects of past US carsharing programs and analyzed the evolution of carsharing and its various business models.

Concrete is also responsible for over 8% of annual anthropogenic greenhouse gas (GHG) emissions globally. As population and urbanization increase and existing infrastructure deteriorates, demand for production of concrete will increase, and with it, the environmental burdens from its production. The models used to determine environmental impacts of producing concrete have considerable uncertainty and variability. This makes it challenging to identify the most effective means of mitigating these burdens.

Researchers at UC Davis reviewed published studies to summarize the range of household- and community-level benefits that can be realized by reducing car dependence in California. This policy brief summarizes the findings of that work.

This policy brief summarizes findings from a research report that examines the fuel-savings and GHG emissions impacts of various eco-driving practices.

This policy brief summarizes findings from researchers who used existing modeling tools and data to understand the potential market demand for a first-mile transit access service in the San Francisco Bay Area.

This policy brief summarizes findings from UC Davis research that examined how the COVID-19 pandemic has impacted the use of ridehailing and other travel behaviors among various sociodemographic groups.

This policy brief summarizes findings and policy implications from research that assessed the administration of the gasoline tax, including collection and distribution of revenues, to determine what barriers and opportunities might exist for a road user charge funding mechanism.

This policy brief assesses state and local Transportation Network Company taxes across the United States and develops a method of comparing per-ride and percentage taxes in order to the examine the likelihood of these taxes encouraging more sustainable travel.

This policy brief summarizes findings from a UC Davis study where researchers compared the cost-effectiveness of existing inter-city transit service in rural disadvantaged communities in California’s San Joaquin Valley to hypothetical ridesharing and carsharing services.

Researchers at the University of California, Davis and the Technical University of Berlin evaluated questions around the impacts of automated vehicles by simulating three scenarios in the Westside Cities area using an open-source, dynamic, agent-based travel model called MATSim, then calculated the benefits of each scenario compared to the base case for various income groups.
