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…

Identifying and Measuring Transportation Challenges for Survivors in Intimate Partner Violence Shelters
Sarah Leat
Environmental stressors within the built environment can greatly impact health. Environmental stressors, such as noise levels, crowding, and housing quality have been shown to impact physical healing as well as mental health. Although environmental stressors have been examined within healthcare environments, such as hospitals and clinics, very little research exists about the presence of environmental stressors within shelter environments. Furthermore, even less research has looked at…
