||Vector-based GIS is used as a basic for building a predictive model of car-borne recreational activities in Danish nature areas. Special attention is paid to the forests. The model takes its point of departure from frequencies of forest visits considering type of starting point (dwelling, summer house etc.), travel cost (into four time-bands) and three different nature types (forest, beach, and the remainder landscape). By means of linear regression statistics the model results are correlated with registered activities (number of cars in an extensive selection of parking lots in the nature). Further the effect of various local amenities – distance to the coasts, terrain form etc. – are evaluated. The work is part of the authors Ph.D.-thesis (Skov- Petersen, 2002).
