Research Highlights

Applying an Equity Lens to Automated Payment Solutions for Public Transportation

Anne Brown , Candace Brakewood , John MacArthur
Our multi-year study on automated transit fare collection offers a key finding that won't surprise you: Despite the convenience, the rush toward cashless fare systems has created barriers for lower-income riders seeking to use transit. Results from focus groups, surveys, and a review of current transit agency practices suggest that continuing to accept cash is a crucial way to keep transit accessible. However, dealing with cash has drawbacks: it’s time intensive and expensive. Using a detaile... Read More

Novel Approaches to Model Travel Behavior and Sustainability Impacts of E-Bike Use

John MacArthur
Christopher Cherry
Electric bikes (e-bikes) are a new mode of transportation that could substantially improve efficiency in the transportation system if adopted as substitutes for cars. Researchers at University of Tennessee, Knoxville, Portland State University, and Bosch E-Bike Systems have received funding from the National Science Foundation to measure real-world travel behavior and assess the sustainability impacts of those choices. We are developing a platform that is easily deployable, non-invasive, and... Read More
