INTR 5100 Traffic Flow Theory
2023 Fall
Emerging technological innovations in autonomy, connectivity, and machine learning are revolutionizing vehicular traffic systems. The need for a comprehensive and systematic comprehension of traffic dynamics has become imperative to harness these innovations and reshape transportation systems. The course covers fundamentals of vehicular traffic flow dynamics and their various applications in traffic control. This course starts with how to obtain and interpret traffic flow data, which serves as the bedrock of quantitative traffic modeling. The second and main part delves into various approaches and models that offer mathematical descriptions of vehicular traffic flow, spanning from the microscopic to macroscopic level. The third part introduces major applications of traffic flow theory including classic traffic management schemes, mix-autonomy traffic flow modeling and advanced control and sensing strategies by connected and automated vehicles. Students will be able to grasp key concepts and the physics behind various traffic phenomena, and have a better understanding of driving behaviours and intelligent traffic management from a systematic level. This course is designed to help students develop fundamental skills of transportation field and knowledge, connect with the state-of-art transportation problems and equip them for more advanced studies in intelligent transportation systems.
INTR 5300 Nonlinear Control Systems
2023 Spring
This course introduces methods for analysis and control design of nonlinear systems, which have a wide range of engineering applications including transportation, robotics, biology, energy, and manufacturing systems. The course includes: 1) Mathematical models of nonlinear systems, and fundamental differences between the behaviour of linear and nonlinear systems, equilibrium, limit cycles and general invariant sets. 2) Phase plane analysis, Lyapunov stability, Input-to-state stability, Input-output stability, and approximation methods. 3) Feedback linearization and nonlinear control design tools, including Lyapunov-based control and Backstepping.
