Abstract:

In this talk, I will share some results from our recent research that intends to transform transportation network equilibrium modeling paradigm via end-to-end learning. Our research was motivated by observing that existing equilibrium analysis paradigm has been established via a “bottom-up” approach, in which, e.g., the selection of behavior model for travel choices or the calibration of the supply function, is divorced from the end goal of the model building, i.e., prescribing an equilibrium flow distribution that matches observations as closely as possible. Leveraging recent advancements in game theory and machine learning, we hope to develop an end-to-end framework that directly learns the demand- or/and supply-side components and the equilibrium state from empirical data.
