Policy Briefs

The NCST produces two-page Policy Briefs to help summarize and synthesize findings from its research and to highlight the policy and/or practice implications in an easy-to-understand, accessible style and format.

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.

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.

Congestion Reduction via Personalized Incentives

Research Product Type
Research Brief
Researchers at the University of Southern California developed a real-time, distributed algorithm for offering personalized incentives to individual drivers to make socially optimal routing decisions.

Why are Some California Consumers Abandoning Electric Vehicle Ownership?

Research Product Type
Policy Brief
This policy brief summarizes findings from research that surveyed California PEV buyers 2–7 years after they first purchased their EV to understand whether they have continued to choose PEVs with subsequent purchases, and if not, what factors may have led to their discontinuance of the technology.

The Sustainability of Alternative Last-Mile Delivery Strategies

Research Product Type
Policy Brief
This policy brief summarizes findings and policy implications from UC Davis research that developed models for e-commerce demand, last-mile delivery operations, and cost and sustainability assessment, then applied this modeling framework to a case study in Southern California to evaluate the potential impact of these strategies under different delivery scenarios

Can Complete Streets Deliver on Sustainability?

Research Product Type
Policy Brief
This policy brief summarizes findings from UC Davis research that used life cycle assessment, a modeling tool for evaluating a product or activity’s environmental impacts through all stages of its life, to quantify the environmental performance of complete streets.
