The perturbed utility route choice model

The perturbed utility route choice (PURC) model has some attractive features. It needs no choice set generation but uses the complete network as it is. Moreover, it generates realistic substitution patterns directly from the network structure. With aggregate data, the model can be estimated by plain linear regression. The talk will introduce the model and give an overview of some current research. One research project develops an estimator suitable for large datasets of observed route choices in large networks. Another ongoing project develops a fast equilibrium assignment algorithm suitable for large-scale applications.

Mogens Fosgerau is a professor of economics at the University of Copenhagen. His ERC Advanced Grant developed theory and applications for perturbed utility discrete choice models, a new kind of models that go beyond the classical random utility discrete choice models. Continuing this line of research, he is currently developing a new kind of route choice model based on perturbed utility. He has previously worked, inter alia, in microeconomic theory, discrete choice, travel time variability and scheduling, traffic congestion, the value of travel time, and route choice models.
