This paper presents some results from the 'overdraagbaarheid' study, an experiment conducted recently in the netherlands in which an entire regional travel demand model system was transferred from one region to another. The aim of the experiment was to explore the extent to which results obtained in the first study were replicated in the second. The conclusions, which are summarised below, were sufficiently encouraging to proceed to the stage of developing techniques to implement transfers of such model systems without the costly and time-consuming purpose-designed transportation survey which usually precedes such modelling effort. Rather than an abstract or general treatment of the subject, the focus of the paper will thus be on the practical significance of model transferability, and that in the context of one particular set of travel demand models. However, emphasis will be given to the interpretation of the concept and the transfer procedures in terms of an underlying behavioural model, namely individual random utility maximisation subject to constraints.
