Promoting Environmental Justice Populations’ Access to Opportunities within Suburban Boomtowns: An Interdisciplinary, Mixed-Methods Approach to Addressing Infrastructure Needs

Jandel Crutchfield Courtney Cronley , Kate Hyun
In the last twenty years, the population increased over 100% in Collin County, Texas. The county is projected to have over 2.4 million residents by 2050 -- more than three times its population in 2010. When enough people flock to an area to call it a boomtown, the population tends to grow much faster than the infrastructure to support it. Where does that leave mobility options for residents? Researchers from the University of Texas at Arlington's (UTA) School of Social Work and College of… Read More

V2X: Bringing Bikes into the Mix

Stephen Fickas
This project focuses on a type of transportation that is currently left out of V2X conversations: bicycling. The project demonstrates how an inexpensive system can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system proposed and demonstrated integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device… Read More
