Samenvatting
The CADSS project (Concentration and Deconcentration Simulation Study) deals with the development and application of a disaggregated spatial allocation model. In this paper attention is focused on the calibration of the aggregated model. Successively will be presented the calibration of the allocation of intermediate basic employment and the interactions of a shopping model. The most important characteristic of the submodels is the introduction of the residential environment as attraction factors and a more- dimensional attraction function.
