Problem: Over-tourism, the above-average increase of tourists in certain regions, has negative impacts on the inhabitants, the visitors, and the environment of a certain destination. Visitor flows should be distributed to different destinations in such numbers that the individual region can handle the number of tourists without over-affecting the environment.

Solution approach: In a data service ecosystem, several data sources are sovereignly linked: tourism data from three partner communities and the tourism organization, weather data from a weather service, and anonymized and aggregated cellular location data from a mobile operator. A customer flow analysis is thus created by a data service provider, which helps the participating tourism regions to address customers in a more targeted manner and to better direct and distribute them in the region.
