Projects (Pre-2025)

The National Center for Sustainable Transportation has funded a variety of research grants, organized by our three research themes (Infrastructure Provision; Travel Demand; and Vehicle Technology), and by project type (applied research projects, white papers / research synthesis, seed grants, translational projects, dissertation grants, and graduate student-led research). 

National Impacts of E-commerce Growth - Development of a Spatial Demand Based Tool

  • Principal Investigator Miguel Jaller, Ph.D.
  • University of California, Davis
This study addresses how much e-commerce will grow, if the growth will be consistent across locations and demographics, and what the impacts on the transportation system will be. In doing so, the study will develop a tool to estimate VMT and emissions from varying e-commerce scenarios using transportation demand models.

Annual Investigation of Nationwide Mobility Trends: “The Pulse of The Nation” on the 3 Revolutions

  • Principal Investigator Giovanni Circella, Ph.D.
  • University of California, Davis
The study will shed light on the evolving impacts of new mobility options on various components of travel behavior and vehicle ownership, how these solutions expand travel options and the circumstances under which travelers increase travel multimodality and may reduce their reliance on the use of private vehicles.
