This 20-minute conference talk from the Eclipse Foundation explores how digital twins (DiTs) can revolutionize municipal traffic management through a novel system called Digital Twin-Aided Municipal Traffic Control (DiTAT). Learn how DiTAT leverages real-time video imagery from roadside surveillance cameras to extract critical traffic data including vehicle start times, speeds, and movement patterns. Discover how the system uses SUMO (Simulation of Urban MObility), an open-source traffic simulator, as a digital twin of physical roadway configurations to test various traffic light settings and identify optimal control strategies. The presentation demonstrates the continuous feedback loop between the digital simulation and physical traffic infrastructure, showing how this bidirectional interplay enables reactive, window-by-window optimization of traffic flow. Presented by Shelby Williams and co-authored by a team of researchers including Sercan Aygun, Reeti Pradhananga, Li Chen, Yazhou Tu, Whitney Crow, Sathyanarayanan Aakur, and Nian-Feng Tzeng, this talk highlights how DiTAT significantly improves transportation performance in real-world traffic scenarios.
