Research Highlights

Connected Streetcar Project

Principal Investigator: Kristin Tufte

Co-Investigators: Larry Head , John MacArthur

This project will create a foundation for deploying connected vehicle infrastructure and facilitating connected vehicle research for the NITC UTC. Connected Vehicle (CV) technology and the associated data has the potential to help us better understand vehicle, streetcar, and transit performance as well as improve safety for vehicles, pedestrians and bicyclists. Specifically, this project will deploy the Multi Modal Intelligent Traffic Signal System (MMITSS) — a Dynamic Mobility Application th... Read More

Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

Principal Investigator: Sirisha Kothuri

Co-Investigators: Joseph Broach , Nathan McNeil , Kate Hyun , Stephen Mattingly

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes. To date, the bulk of our information on bicycling activity has come from national and regional household travel surveys or observed counts of cyclists -- either short-duration manual or longer-term automated counts -- in a limited set ...
