At the end of the 1960's, a number of so-called large scale planning models were built. Objections were raised against these models of which those of D.B. Lee (1973), formulated in his "Requiem for Large Scale Models" attracted quite some attention. In the last 25 years, however, a considerable number of developments took place in availability of data, computer hardware and graphical and other software tools. It has become much easier for large scale model builders. To demonstrate the possibilities for large scale modeling a model is described in which the demographic development, the distribution of the households over the dwellings and the spatial distribution of employment form the basis for the spatial distribution of human activities in general and vehicle road traffic in particular. The model can be applied as a spatial planning model as the planning of land use, location of dwellings and the attributes of the road system can be manipulated to study the effects on a number of human activities. Micro-simulation methods are applied. (A)
