Hi there, I am Rusi Wang (Chinese name: 王铷锶), and you can call me “Royce”. I was born in February 1999 in Shanghai, China. I am currently a Ph.D. candidate at the Urban Mobility Institute, Tongji University.

I have been fascinated by maps since childhood. During my undergraduate studies at the University of Electronic Science and Technology of China, a course sparked my interest in studying networks. This interest has since grown into my research on transportation network modeling and optimization.

Since August 2024, I have been conducting my Ph.D. research under the supervision of Professor Chi Xie, with a primary research interest in network modeling and optimization. My Ph.D. dissertation focuses on travel demand management (TDM) in dynamic equilibrium traffic networks. A key contribution of my work is the development of an analytical dynamic traffic assignment (DTA) model that is computationally tractable for large-scale networks and accommodates multimodal transportation (e.g., solo driving, e-hailing, carpooling, public transit, and combined modes). Based on this equilibrium model, I analyze and solve a class of TDM strategy (e.g., congestion pricing, tradable mobility credit, and booking cum rationing) optimization problems with specific mathematical structures. I have also developed Loopano, software that brings these models into an interactive environment for computing, analyzing, and visualizing transportation network equilibria, and I continue to refine and extend its capabilities.
