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 Impact of Ridehailing on Other Travel Modes and on Vehicle Dependency

Research Product Type
Policy Brief
Researchers at the University of California, Davis surveyed California residents about their personal attitudes and preferences, lifestyles, travel patterns, vehicle ownership, adoption and use of new mobility services, and personal and household characteristics, and this brief summarizes the results of multiple studies that have used this dataset to generate insights into the impact of ridehailing services on the use of other travel modes and on car ownership prior to the COVID-19 pandemic.

Electric vehicle lithium-ion battery recycled content standards for the US – targets, costs, and environmental impacts

Research Product Type
Associated Publication
Lithium-ion battery recycling can decrease life cycle environmental impacts of electric vehicles (EVs) and assist in securing domestic supply chains; however, the US has no policies for recycling of batteries at their end-of-life. This analysis calculates feasible RCSs for the US based on future sale projections, techno-economic assessment, life cycle assessment, and material flow analysis.

Georgia Express Lane Corridors Vehicle Occupancy and Throughput Study 2018-2020 - Volume I: Vehicle and Person Throughput Analysis Before and After the I-75 Northwest Corridor and I-85 Express Lanes Extension

Research Product Type
Research Report
This report summarizes the vehicle and person throughput analysis for the I-75 Northwest Corridor (NWC) and I-85 Express Lanes in Atlanta, GA, undertaken by the Georgia Institute of Technology research team for the State Road and Tollway Authority (SRTA).

Case Studies of Socio-Economic and Environmental Life Cycle Assessment of Complete Streets

Research Product Type
Research Report
“Complete streets” is a design concept for primarily urban streets and intersections (existing and/or new) intended to encourage active transportation by bicyclists and pedestrians by making streets safer, convenient, and attractive for active transportation. This project seeks to provide insight into specific and different potential benefits of a given complete streets project.

The Costs of Owning Battery-Electric Trucks – Is the Research Aligning?

Research Product Type
Policy Brief
Researchers at the University of California, Davis reviewed 10 recent studies of the total cost of ownership of battery-electric trucks, now and in the future, compared to a baseline diesel truck to derive general findings that are robust across all the studies.

Variable Speed Limit Control to Reduce Traffic Congestion in the Face of Uncertainty

Research Product Type
Research Brief
Researchers at the University of Southern California developed, analyzed, and evaluated an innovative approach to alleviate highway bottleneck congestion, which includes issuing variable-speed advisories and lane-change recommendations when needed to the upstream vehicles, as well as ramp control to manage incoming traffic, while accounting for inaccuracies in traffic data and road information and the complex behavior of human driving.

Evaluating Pilot Approaches to Increase Rural Mobility

Research Product Type
Policy Brief
Researchers at the University of California, Davis evaluated three innovative mobility pilot programs in the San Joaquin Valley to understand the participant characteristics and outcomes of each pilot.

Exploring Solar Charging Station Design for Electric Bicycles

Research Product Type
Research Report
The goal of this project is to serve as an off-grid energy power supply and environmental information center, with interactive displays of the solar station operation and an LED display of local air quality. 

A Before and After Evaluation of Shared Mobility Projects in the San Joaquin Valley

Research Product Type
Research Report
In rural areas, cost-effective transit service is challenging due to greater travel distances, lower population densities, and longer travel times than in cities. UC Davis partnered with the eight San Joaquin Valley Metropolitan Planning Organizations to identify and support development of three innovative mobility pilot concepts for the region.

A Glimpse of Microtransit at an Early Stage: The SmaRT Ride Consumer Market in the Sacramento Area

Research Product Type
Policy Brief
Microtransit can potentially offer greater efficiency and more equitable service than ride-hailing services, and it may fill gaps in traditional transit services. Aiming to fill this gap, in 2021, researchers at the University of California, Davis conducted focus groups and an online survey of SmaRT Ride adopters and users of other means of transportation in the Sacramento area.
