The National Center for Sustainable Transportation primarily publishes research reports, white papers / research synthesis papers, and policy/research briefs. NCST funding also supports the production of journal articles, conference papers, books, dissertations, theses, presentations, posters, and more.

Development of an Innovation Corridor Testbed for Shared Electric Connected and Automated Transportation

Research Product Type
Research Report
As part of the City of Riverside’s Smart-City initiative, UC Riverside researchers have developed an Innovation Corridor testbed for enabling shared electric connected and automated transportation research. The testbed supports various transportation modes including passenger vehicles, trucks, transit (e.g., RTA buses), bicycles, and various forms of micro-mobility.

Costs, Reliability, Vehicle Characteristics, and Incentives are the Top Factors Influencing Freight Vehicle Technology Choices

Research Product Type
Policy Brief
California has set goals for transitioning the freight sector to near-zero-emission and zero-emission vehicles (ZEVs). California offers several incentive programs to encourage adoption of ZEVs, but purchase decisions are driven by complex factors beyond simple purchase price. Researchers at UC Davis deployed a stated-preference survey of fleet and carrier companies to collect information about vehicle purchase preferences and how they might be influenced by various incentive programs.

Curbside Management Is Critical for Minimizing Emissions and Congestion

Research Product Type
Policy Brief
Researchers at the University of California, Davis conducted a review of practices in curbside management, and they conducted simulations to evaluate the impact of different management and design strategies on travel time, congestion, vehicle travel, and emissions in residential, commercial, and mixed-use neighborhoods in San Francisco.

Plug-in Electric Vehicle Diffusion in California: Role of Exposure to New Technology at Home and Work

Research Product Type
Research Report
The market for plug-in electric vehicles (PEVs) that primarily include battery electric vehicles (BEVs) and plug-in hybrid vehicles (PHEVs) has been rapidly growing in California for the past few years. Given the targets for PEV penetration in the state, it is important to have a better understanding of the pattern of technology diffusion and the factors that are driving the process. Using spatial analysis and Poisson count models, the researchers identify the importance of a neighborhood effect (at home locations) and a workplace effect (at commute destinations) in supporting the diffusion of PEV technology in California.

Exposure to Electric Vehicle Technology at Home and Work Can Fuel Market Growth

Research Product Type
Policy Brief
This policy brief examines the adoption of plug-in electric vehicles in California between 2014 and 2016, both spatially and temporally, to gain a better understanding of the technology diffusion process and the effect of technology exposure, while controlling for sociodemographic factors and the effect of PEV incentive programs on PEV adoption in the state.

Across Early Policy and Market Contexts, Women and Men Show Similar Interest in Electric Vehicles

Research Product Type
Policy Brief
The transition to electric vehicles (EVs) will rely, ultimately, on the participation of all vehicle buyers. Researchers at UC Davis examined whether the gender similarities in prospective interest in EVs witnessed in California extended to other states that, while generally supportive of California’s EV goals and signatories to many of California’s air quality standards had less supportive policy frameworks, fewer EV sales, and less EV charging infrastructure in 2014.

Across Early Policy and Market Contexts Women and Men Show Similar Interest in Electric Vehicles

Research Product Type
Research Report
While ownership and purchase of all vehicles approach gender parity, to date electric vehicles (EV) are being purchased by far more men than women. Prior analysis from California finds no reason in the available data why this difference persists. This report extends that analysis across 12 other U.S. states with varying, but generally less supportive than California, EV policy and market contexts.

Empirical analysis of the role of incentives in zero-emission last-mile deliveries in California

Research Product Type
Associated Publication
This paper evaluates the role of incentives for zero and near-zero emission vehicle (ZEV) technologies in last-mile delivery operations. Specifically, the study investigates the total cost of ownership and life cycle environmental impacts associated with last-mile deliveries, and compares the private and public costs of different vehicle powertrain and fuel pathways, under existing incentives in the State of California.

Consideration of Automated Vehicle Benefits and Research Needs for Rural America

Research Product Type
Research Report
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.

Workforce Development Needs of Transportation Sector Climate Adaptation Professionals

Research Product Type
White Paper
This white paper assesses the workforce development needs and current training opportunities related to transportation-sector climate adaptation. To do so, training needs were examined and opportunities identified by state and regional transportation agencies; training needs of aspiring and early-career climate adaptation professionals were cataloged; and a scan was completed of the educational opportunities in climate adaptation currently offered by universities in the United States.
