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
