Decisions regarding the location of motorway interchanges need to be made very carefully because of their economic and political implications. In this paper, we present three optimization models aimed at assisting road administrations when they deal with motorway interchange location problems. The decisions are assumed to be made from the perspective of road users, with the objective of minimizing travel costs. Two of the models are based on existing hub location models, whereas the third one is a new model. The usefulness of the models in real-world situations is illustrated with a case study involving A25, one of the most important Portuguese motorways. When applied to this case study, the new model performed in general clearly better than the other two. [ABSTRACT FROM AUTHOR]
