The National Center for Sustainable Transportation's primary output from research was reports and white papers. Many projects also produced a Project Brief to summarize and highlight the policy and/or research findings and implications. NCST research has also produced journal articles, conference papers, books, dissertations, theses, presentations, and posters. The NCST has also created various tools that can be used by policymakers and practitioners, such as models, calculators, and planning tools.

Personalized Coordinated Routing with Utility Learning

Research Product Type
Research Brief
This research proposes a utility learning mechanism to estimate drivers' routing preferences for coordinated routing systems. This research brief discusses the results and effectiveness of the coordinated routing system and the utility learning mechanism.

Modeling Traffic Noise and Light on Natural Landscapes at the State Scale

Research Product Type
Research Report
In this report, the authors developed California-wide models of traffic noise and light intrusion into areas adjacent to state highways to aid understanding of wildlife responses to noise and light, and to aid locating and designing crossings to maximize wildlife approach and use.

Data Collection of Odometer Images via WhatsApp to Measure Vehicle Miles Traveled

Research Product Type
Research Report
In this study, to fulfill the gap between current data collection strategies, the authors introduce a WhatsApp-based VMT data collection framework that lets study participants submit photos of their odometer, communicates with them for administrative events, manages submitted images and other information of the participants, and displays that data on the web UI for the study administrator.

Youth Cruz Free: Fare Free Bus and Ridership Behavior among Santa Cruz County Teens

Research Product Type
Research Report
This study examines a Youth Cruz Free program launched by the Santa Cruz METRO in March 2023, allowing kids and teenagers of school age to use the service for free. The researchers were interested in understanding how the program has changed the travel behavior of teenagers, whether it encourages adolescents to use the service after they turn 18, and what factors influence their overall ridership of Santa Cruz METRO.

MOVES 4.0 Updates for the Fuel and Emissions Calculator (FEC)

Research Product Type
Research Report
This project employs the outputs from MOVES-Matrix 4.0 to generate a data set that can be employed by users of the 2018 Fuel and Emissions Calculator (Version 3.0) to update energy use and emission rates to reflect the latest outputs from the U.S. Environmental Protection Agency’s MOVES 4.0 energy use and emission rate model for the Atlanta, Georgia summer scenario.

Dataset: Data for: Solar bike path feasibility study in California

Research Product Type
Data
This is the dataset for project "Shifting Gears to Sustainability: A Deep-Dive into Solar-Powered Bike Pathways" (UCR-CT-FAST-086). This project explores the feasibility of integrating solar-powered infrastructure into bike pathways as a sustainable energy and transportation solution for California.

Electric Truck Fleet Management under Limited and Uncertain Charging Infrastructure Availability

Research Product Type
Research Report
This study develops a comprehensive optimization framework for electric truck fleet management, addressing the interplay between infrastructure limitations, operational uncertainties, and energy cost fluctuations. This research will also provide scalable insights for policymakers and industry leaders, supporting the broader transition to sustainable freight transportation.

Exploring the Equity Effects of VMT Mitigation Measures

Research Product Type
Research Report
The authors investigated the equity effects of vehicle miles traveled (VMT) mitigation measures, developed a framework for evaluating those effects at the project level, and then applied the framework to two highway expansion case studies in California.
