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…

The Use of Mt. Mazama Volcanic Ash as Natural Pozzolans for Sustainable Soil and Unpaved Road Improvement
Matthew Sleep
This Small Starts study offers sustainable road building materials for rural infrastructure, from an unlikely source. Approximately 7,000 years ago, the eruption of Oregon's Mt. Mazama blanketed the Klamath Basin region with a thick layer of volcanic ash. Matthew Sleep, an associate professor of civil engineering at Oregon Tech, investigated the use of this ash as a natural pozzolan for soil stabilization and unpaved roadway improvement. He found that the ash, prevalent in Southern Oregon, has…
