Transportation Icons

The National Center for Sustainable Transportation funds a variety of research grants, organized by our four research themes (Environmentally Responsible Infrastructure and Operations; Multi-Modal Travel and Sustainable Land Use; Zero-Emission Vehicle and Fuel Technologies; and Institutional Change), and by project type (applied research projects, white papers / research synthesis, seed grants, translational projects, dissertation grants, and graduate student-led research). 

Routing of Battery Electric Heavy-Duty Trucks for Drayage Operations

  • Principal Investigator Maged Dessouky, Ph.D.
  • University of Southern California
In this study, the researchers will use optimization and simulation modeling to explore the impacts of using battery electric heavy-duty trucks (BEHDTs) in freight operations (e.g., fleet size) and emissions, taking into account differences in performance and refueling.

Integrating Micromobility with Public Transportation

  • Principal Investigator Beth Ferguson
  • University of California, Davis
This project builds off of a previous project nearing completion (Designing Public Transit Stations to Enhance Access to First/Last Mile Mode Choices) by continuing stakeholder interviews, updating ArcGIS map files (bicycle lane, operator zones, transit stations), exploring travel behavior, and monitoring best practices to increase micromobility and public transit ridership post-COVID-19.

All Aboard! Easier Transit Travel with Standardized Payments

  • Principal Investigator Susan Pike, Ph.D.
  • University of California, Davis
This research will examine the potential for the adoption of a standardized fare payment system throughout California’s transit operators; to better serve their customers and provide seamless trip-planning and payment.

Factors Impacting Mode Share Changes in California

  • Principal Investigator Susan Pike, Ph.D.
  • University of California, Davis
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.

Optimizing Bikeshare Service to Connect Affordable Housing Units with Transit Services

  • Principal Investigator Miguel Jaller, Ph.D.
  • University of California, Davis
This project will develop a framework to optimize the location of bikeshare stations to mitigate the barriers between affordable housing and transit services. To achieve this, the multi-objective optimization process will consider both bikeshare trip demand, transit service schedule, available affordable housing units, and other geographic information.

Understanding the Influence of Local Option Sales Tax Measures on SB 375

  • Principal Investigator Elisa Barbour, Ph.D.
  • University of California, Davis
This research project will assess how county sales tax measures affect funding allocations and policy and program choices adopted in MPO long- and short-range plans in California’s four largest regions. With San Francisco Bay Area policymakers currently seeking to place a multi-county sales tax measure on the ballot, now is an opportune time to investigate these challenges and opportunities.

Bicycling as a Solution to Yosemite Valley Traffic

  • Principal Investigator Susan Handy, Ph.D.
  • University of California, Davis
Yosemite National Park attracts 4.5 million visitors a year, 60% of whom spend at least some time in Yosemite Valley where many of the park’s natural wonders are found. Bicycles have been a popular travel alternative within the valley. The purpose of this project is to explore the potential for bicycling to play a larger role in the effort to manage Yosemite Valley traffic and reduce environmental impacts.

Studying the Impacts of the Pandemic and Future Mobility Patterns in California During the Post COVID-19 Recovery

  • Principal Investigator Giovanni Circella, Ph.D.
  • University of California, Davis
Starting in early 2020, the world has experienced huge disruptions due to the COVID-19 pandemic. The analyses carried out in this study will shed light on the complicated impacts of the COVID-19 pandemic on activity participation and travel patterns, including commuting and non-commuting (e.g., discretionary) trips, and the use of various means of travel.

Emissions Impact of Electric Vehicle Adoption on Disadvantaged Communities

  • Principal Investigator Alan Jenn, Ph.D.
  • University of California, Davis
As electric vehicles are being adopted in relatively wealthier communities, there is a question as to whether pollution is being shifted from these communities to more disadvantaged, lower income communities which tend to be located near fossil fuel power plants. This project proposes to conduct a high-resolution accounting and measurement of the emissions and associated impacts through three phases of research.

Developing a Vehicle Cost Calculator to Promote Electric Vehicle Adoption among TNC Drivers

  • Principal Investigator Angela Sanguinetti, Ph.D.
  • University of California, Davis
This research will develop a total cost of ownership (TCO) model and online vehicle cost calculator (VCC) for transport network company (TNC) drivers. Many VCCs have been developed to support consumers in calculating the relative costs of electric and gas vehicles, but their design and the TCO models that underlie them are geared toward traditional vehicle ownership.

Democratization of Electric Vehicle Charging Infrastructure

  • Principal Investigator Adam Davis, Ph.D
  • University of California, Davis
The electrification of privately owned vehicles is a necessary step to eliminating transportation greenhouse gas emissions. The adoption of electric vehicles so far has been heavily focused among high-income commuters who live in major metropolitan areas.

Examining e-Bike Rebates in California

  • Principal Investigator Dillon Fitch, Ph.D.
  • University of California, Davis
Given the increase in demand and incentives for e-bicycling; this project seeks to evaluate the behavioral effects (change in bicycling, driving, use of transit) of these incentives to help guide future policy interventions for e-bicycling. The researchers will examine these changes based on survey data, and will propose future study designs for more in-depth analyses and evaluations of e-bike incentives.
