Advancing Safety At Intersections: Measuring The Effectiveness Of Traffic Signal Strategies For Speed Management On Operations And Safety
Sirisha Kothuri
Many states are adopting the Safe System approach (USDOT, 2022) to improve traffic safety. As the role of speed in injury severity is becoming increasingly clear, one of the key elements of a Safe System approach is Safer Speeds. Specifically, higher motor vehicle speeds lead to higher injury severity during a collision, especially for nonmotorized users (Rosén and Sander 2009; Tefft 2013) who are the most vulnerable users in the transportation system. Most pedestrian crashes occur on higher-...

Understanding Human-centered AI through Data Integration and Analytics
David Yang
Human Centered Artificial Intelligence (HCAI) is an approach to developing and implementing Artificial Intelligence technology applications that focuses on the needs of individuals and communities who utilize these applications. This project intends to develop course modules and tools for students to understand human-centered AI methods and data requirements, conduct specific mobility analysis using AI-empowered technologies, and build multimodal technology solutions to improve mobility. The ...
