AuthenticusHi 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 obtained my B.Eng. degree from the University of Electronic Science and Technology of China [Rank]Project 985Double First-Class University (Class A)QS World University Rankings 2027: #=488U.S. News Best Global Universities 2026–2027: #=152 in 2021 and my M.Sc.(Eng.) degree from Tongji University [Rank]Project 985Double First-Class University (Class A)QS World University Rankings 2027: #146U.S. News Best Global Universities 2026–2027: #110 in 2024. I am currently a Ph.D. candidate at Urban Mobility Institute, Tongji University.
Since August 2024, I have been conducting my Ph.D. research under the supervision of Professor Chi Xie at the Transport and Energy Systems Laboratory (TESLA) [📍Location], 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.

Chi Xie*, Rusi Wang, Dianlei Wang, et al.; Pre-dissertation research
- Addresses the freight subsidy optimization problem based on a multimodal multicommodity network equilibrium model.
- Considers the carrier’s revenue loss and shippers’ congestion surcharge simultaneously.
- Compares the proposed optimization scheme with the currently implemented subsidy scheme to demonstrate its effectiveness.
