Research Highlights

Understanding the Impact of Decentralizing Homeless Services on Transportation and Mobility in Salt Lake County

Sarah Canham Ivis Garcia , Jeff Rose , Shannon Jones
How can relocating services away from a downtown center change the transportation decisions and patterns for persons experiencing homelessness? And how do those changes affect access to the services they need? New research from the University of Utah (UU) examines the impacts of decentralizing homeless service locations through a case study in Salt Lake County, Utah. Prior to 2019, resources for people experiencing homelessness in the county were concentrated in a single location: The Road… Read More

Fast Track: Allowing Bikes To Participate In A Smart-Transportation System

Stephen Fickas Marc Schlossberg
This project focuses on a mode of transportation that is currently left out of V2X (vehicle-to-everything) conversations: bicycling. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to give bicyclists the same technology appearing on modern vehicles: Green Light Optimized Speed Advisory (GLOSA). GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a “green wave” (i.e.,… Read More
