Research Highlights

E-Scooters and Public Health: Understanding the Implications of E-Scooters on Chronic Disease

Nicole Iroz-Elardo
E-scooters are an emerging micromobility transportation option with implications on transportation systems and public health. To date, most research on public health and E-Scooters has focused on safety implications. Health implications other than injuries are likely, but there has been no investigation to date of e-scooter impacts on chronic disease. For example, there is some indication that e-scooters are replacing some auto trips with about a third of users self-reporting the trip would… Read More

Exploring Data Fusion Techniques to Estimate Network-Wide Bicycle Volumes

Sirisha Kothuri Joe Broach , Nathan McNeil , Kate Hyun , Stephen Mattingly
In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where. Traditional bicycle counters can provide data for limited sections of the bike network, often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only… Read More
