Vehicle Sensor Data (VSD) Based Traffic Control in Connected Automated Vehicle (CAV) Environment

Xianfeng (Terry) Yang
It can be expected that automated vehicles and human-driven vehicles will coexist in the transportation network for quite some time. In order to support various traffic control tasks it is critical to develop a reliable model to understand the real-time traffic patterns in this mixed environment. A new report from the National Institute for Transportation and Communities (NITC) contributes three new tools to help planners model freeway traffic with both connected automated vehicles (CAVs) and… Read More

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
