Abstract

In the present paper the structure of the demand model framework for the new Danish national model is outlined. It involves a discussion at two levels. At the framework level, we discuss how demand is modelled in a number of parallel sub-models and how these are linked. An issues is to represent all transport but on the other hand avoid double counting.
At the sub-model level, special attention is given to the week-day model. As the model for week-day traffic are the most important components with respect to overall mileage and congestion it is particular important from a policy point of view. We discuss in more details the design of tours (trip chains) and how these will be organised into primary and secondary tours with intermediate stop activities. Finally, we discuss how activity chains can be represented in a matrix form prior to the assignment procedure.
