Publications

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.

The Impacts of Automated Vehicles on Center City Parking Demand, Congestion, and Emissions

Research Product Type
Policy Brief
Researchers at the University of California, Davis modeled the travel effects of changes in drop-off and pick-up activity and parking supply that might be triggered by widespread automated vehicle use in San Francisco’s city center. This policy brief summarizes the findings from that research and provides policy implications.

Alkali-activated Materials: Environmental Preliminary Assessment for U.S. Roadway Applications

Research Product Type
Research Report
To increase the adoption of Alkali activated materials concrete for civil applications such as pavements, it is fundamental to analyze the existing literature to clarify the link between environmental and mechanical performance, identifying opportunities for applications that are tailored to the local availability of raw material, reducing transport environmental costs.

Climate Action Plans Should Quantify Life Cycle Greenhouse Gas Emissions and Costs to Achieve Meaningful, Cost-Effective Emissions Reductions

Research Product Type
Policy Brief
Researchers at the University of California, Davis developed a decision support framework for local governments to assess life cycle greenhouse gas reductions and costs of Climate Action Plan strategies. The researchers demonstrated their approach by developing marginal abatement cost curves for two California counties, Yolo and Unincorporated Los Angeles, based on strategies from their respective Climate Action Plans. This policy brief summarizes findings from that research.

Fuels and Fuel Technologies for Powering 21st Century Passenger and Freight Rail: Simulation-Based Case Studies in a U.S. Context

Research Product Type
Dissertation
Rapid technological developments and increased concerns about climate change have spurred interest away from the internal combustion engine and the use of fossil fuels in various applications. These same technologies hold promise in a rail context. This dissertation explores fuel technologies for powering 21st century passenger and freight rail.

Results of the 2019-20 Campus Travel Survey

Research Product Type
Research Report
The 2019-20 survey collected data from 3,098 people affiliated with UC Davis about their travel to campus during a single week in October 2019.

Future Electric Vehicle Charging Demand at Highway Rest Areas and Implications for Renewable Energy Penetration in California

Research Product Type
Policy Brief
This policy brief summarizes findings from researchers at the University of California, Davis, who collected state travel data and electricity demand data to run a model that identified optimal highway rest areas for electric vehicle charger installation and calculated how an increase in charging demand would affect the California electricity grid at selected highway locations.

Using Genetic Tools to Identify Populations Within Species Could Ease Infrastructure Mitigation

Research Product Type
Research Brief
This research brief summarizes findings and implications from the project where researchers at UC Davis sequenced entire genomes for 40 individual Anna’s hummingbirds (Calypte anna) from across California to identify breeding populations and develop a genetic toolkit to assign individuals to those populations. The presence of this species at bridge construction sites has resulted in construction delays in part because little information exists on the status of different populations within the species.

Fostering the Use of Zero and Near Zero Emission Vehicles in Freight Operations

Research Product Type
Research Report
The study collected information through a web-based stated preference survey sent to fleets and carrier companies to gather data about their economics, and their vehicle purchase preferences. The project also developed a multi-criteria decision-making tool using a Spherical Fuzzy Analytical Hierarchy Process based on experts’ knowledge.

Electric Fleet Adoption Strategies – Addressing Storage and Infrastructure Needs

Research Product Type
Research Report
This project evaluated the mid to long-term energy storage needs of the electric grid for select fleet electrification scenarios. The results show that Electrical Energy Storage (EES) capacity requirements depend on a number of parameters, including Demand Response (DR), Electric Vehicle (EV) charging flexibility, and total EV population.

Experiencing Pilot Demonstrations Helps Individual Acceptance of Self-Driving Shuttles

Research Product Type
Policy Brief
Researchers at the University of California, Davis surveyed residents and employees of the West Village area of the UC Davis campus during the three-month pilot deployment of a self-driving, electric shuttle to understand attitudes toward self-driving technology. This policy brief summarizes findings from that research and provides policy implications of self-driving shuttles.

Improving Transportation Information Resilience: Error Estimation for Networked Sensor Data

Research Product Type
Research Report
This project focuses on the problem of error detection and data recovery of partially malfunctioning sensors that could provide valuable information. The results of three network examples with different scales demonstrate the applicability of the proposed method in a large variety of scenarios. This research improves fundamental knowledge on transportation data analytics as well as the effective management of data and information infrastructure in transportation practice.
