Transportation is undergoing deep and significant transformation, seeking to fulfill the promise of connected mobility for people and goods, while limiting its carbon footprint.

We introduce a mathematical paradigm, the Differential Variational Inequality (DVI) and Differential Complementarity Systems (DCS), for modeling and solving equilibrium and similar problems on dynamic transportation networks.
