+description: "<p>Junyi Ji is a Ph.D. student in Civil Engineering and the Institute for Software Integrated Systems at Vanderbilt University. He is dedicated to the development and field control experiments of the I-24 MOTION freeway traffic testbed. His current research focuses on understanding the nature of traffic waves and developing a mathematical digital twin for the freeway testbed. His long-term research vision is to integrate advanced computational methods and CPS technology with transportation to create a sustainable system. </p>
 
-Junyi's primary interest is to better understand the microscopic and macroscopic traffic flow characteristics and to formulate control strategies to improve the efficiency and safety of freeway systems. He is devoted to I-24 MOTION freeway traffic testbed development and field experiments. His current research is focusing on understanding the nature of traffc waves and developing the digital twin for freeway testbed.</p>
