Visitor activities in recreation and tourism areas predicted by prognostic models—depending on meteorological factors

Recreational and protected areas experience everincreasing pressures from recreation and tourism, in particular in densely populated regions. This leads to extensive ecological impacts, and to increasing conflicts between user groups. In order to manage recreational and protected areas within acceptable ecological and social carrying capacities, one needs a profound knowledge of the uses visitors make of this area and a reliable prediction of potential visitor loads and activities.
The results of two monitoring projects of the Institute for Landscape Architecture and Landscape Management allowed the investigation of a prognostic model to predict visitor activities. The study area, the Danube Floodplains National Park, lies in close proximity to the large conurbation of Vienna, the capital city of Austria. This circumstance presents the managers and researchers of the conservation area with a variety of challenging problems, due to the high number of recreationists and the multifaceted visitor structure. Within the framework of these projects, video-cameras were installed at several entrance points to the National Park to monitor recreational activities year round, from dawn to dusk.
The models are based on the dependence of the number of visitors and their activities on external factors such as weather and day of the week. Using linear regression and regression trees these relationships were investigated and used to predict future visitor loads and acitivities. Regression trees seem to be a flexible and intuitive tool for modelling the relationship between the day to day changes of the visitor loads and i.e. the weather.
For the model, a distinction was made between workdays and weekends and/or holidays. The weather was considered in a very differentiated way: Meteorological elements, i.e. temperature, clouds, rain, appear directly as parameters in the models as well as indirectly in comfort indices, e.g. the Physiological Equivalent Temperature (PET).
Using the linear regresson reliable figures can be obtained for the daily totals of visitors as well as for specific user groups with high visitor loads, i.e. hikers and cyclists. The day of the week has the greatest influence on the total number of visitors as well as on individual user groups. The number of cyclists and hikers depends heavily on the comfort index PET. The effects of rain and clouds during the preceding seven days are small. The usage patterns of joggers and dog owners were more difficult to model as they are less influenced by the day of the week and weather related factors.
The regression trees confirm these results and additionally show the interaction between the PET and the meteorological variables that were absent from the linear models. Regression trees allow to identify typical weather and thus recreation scenarios.
Furthermore, the regression trees can be interpreted as a model describing how potential visitors make their decision to visit a recreation area based on the current weather situation, the recent weather of the preceding days, and the respective daily progression of the weather conditions.
