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.

In this report, researchers investigate the institutional structure of the current gasoline tax at the federal level including historical changes, how the tax is collected, and how it is allocated and disbursed to fund infrastructure projects.

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.

This policy brief summarizes findings from two projects that simulated traffic patterns along a section of Interstate 710 near the Ports of Long Beach/Los Angeles, and the use of variable speed limit and lane change control systems to evaluate the potential traffic impacts of these systems.

This dissertation focuses on knowledge discovery and data mining for shared mobility and CAV applications.

This study unravels underlying shopping behaviors–both in-store and online–using the 2016 American Time Use Survey (ATUS) data, and develops an econometric behavioral model to understand the factors that affect shopping decisions.

This policy brief summarizes findings from a study of how the change to using VMT rather than LOS to measure land use projects' transportation impacts affects the approval process for urban development.

This paper presents a statistical meta-analysis of eco-driving feedback studies in order to determine a weighted estimate of the average impact of feedback on fuel economy and explore potential moderators of its effectiveness.

This study explores the potential to promote lower-emissions air travel by providing consumers with information about the carbon emissions of alternative flight choices in the context of online flight search and booking.

This research brief summarizes findings from the associated project, the objective of which was to generate parking assist algorithms that can help truck drivers better plan their trips.

This research brief summarizes the associated project, which developed a methodology that combines urban metabolism and life cycle assessment to examine the life cycle impacts of hardscapes at the urban scale rather than at the product or project scale.

This research explores how road grade impacts the operations of light-duty vehicles and heavy-duty express buses on freeways.

This report provides research findings from the first year of a two-year research project on patterns of local policymaking in California to support transit-oriented development (TOD), transit, and active transport.

This project proposed a hierarchical ramp merging system that not only allowed microscopic cooperative maneuvers for connected and automated electric vehicles on the ramp to merge into mainline traffic flow, but also had controllability of ramp inflow rate, which enabled macroscopic traffic flow control.

In this study, researchers use survey data to analyze bicycling comfort and its relationship with socio-demographics, bicycling attitudes, and bicycling behavior.

This research proposes an adaptive strategy for connected eco-driving towards a signalized intersection under real world conditions.

The goal of this project was to create a genetic toolkit for identifying breeding bird populations and assigning individuals to those populations. Ultimately, such tools could be used to assess population-level impacts when there are conflicts with birds at infrastructure construction sites.

Considerable recent work suggests that Millennials’ behaviors may be converging with those of Generation X as they enter later life stages, but few have investigated whether attitudes, which are often strong predictors of behavior, are undergoing the same convergence. In this study, the authors analyze the existing generational gap in four transportation-related attitudes and examine the differential effects of other characteristics, including life-stage variables, on these attitudinal gaps.
