Résumé / Abstract
The object of this paper is to investigate a bimodal model (private cars and trucks) for transportation tolling. Long distance trips are estimated by a deterministic path based wardrop assignment model, whereas shorter distance trips are modeled by local flows, which are arc based. In this fashion the model recaptures the full scale of trip lengths while retaining a simple structure. Link costs are partly based on travel times, thus the link costs for cars and trucks share common components and are not monotone. Nevertheless it is shown that local flows are uniquely determined, given global flows, and several procedures for calculating the global network equilibrium are described.
