Kvintus. org is a new agent-based simulation tool especially constructed to model recreational behavior integrated with models of animal behavior. The entire model which is available as ‘open source’is based on the generic software package REPAST [4]. Model configuration–in terms of base parameters, entry points, timetables, agent types and state/transitions–are established, manipulated, loaded and saved via XML‑files which enables a high degree of flexibility and user interaction. At run time, agents can be displayed in Google Maps [1]. This way models can be applied in most regions of the World without access to base maps, aerial photos etc. Further–which is probably even more important–using a standard Internet platform like Google Maps it is possible to enable non-expert users to ‘play with’the models and this way focus more on communicative and participatory aspects.
