A Pilot Application of Supernetwork Approach to Multimodal Route Choice The purpose of this paper is to present a model architecture for multimodal transport modelling based on the supernetwork concept, and to propose solutions to a number of issues that hinder implementation. It turns out that the classical network model architecture can be adapted to handle multimodal transport modelling with minor changes, and that the classical concept of network equilibrium is equally applicable in a multimodal transport setting when multimodal transport is cast as travel through a supernetwork..Choice-set generation for route-choice modelling is known as a difficult problem. In this paper we report on the use of stochastic route-finding based on the path utility defined by a recently estimated logit model for route-choice in multimodal networks to efficiently generate plausible routes through a multimodal transport network.
