A model for nationwide travel demand and supply forecasting is described, which combines scenario building, system dynamics and strategic transport modelling. The model facilitates experimentation with alternative policies and perceptions on causalities within the traffic and transportation System. It is based on the 'modelling as learning' approach. It is intended to stimulate experimentation in policy thinking, and to gain an insight into future developments in travel demand and system behaviour on a strategic level. The approach chosen is methodologically hybrid. It can deal both with relationships that have been validated empirically, and subjective perceptions of the system of the analyst or policy maker. A first version of the model is now under development.
