Research Highlights

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

Methodologies to Quantify Transit Performance Metrics at the System-Level

Travis Glick
Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach. ... Read More
