Control

Welcome to the Control Group of TransportLab at the University of Sydney.

Cities are becoming smarter in ways that enable us to monitor, analyze, and improve the quality of life in real-time. Our research mainly targets addressing traffic operations in cities. Our multidisciplinary approach combines physics, engineering, and applied maths through data science, modeling mobility dynamics using relevant mathematical and physical tools, and advanced optimization and control techniques.
