	Abstract = {Large-scale festivals with a multitude of stages, food stands, and attractions require a complex perimeter design and program planning in order to manage the mobility of crowds as a controlled process. Errors in the planning phase can cause unexpected crowd dynamics and lead to stampedes with lethal consequences. We deployed an official app for Zu ̈ri Fa ̈scht 2013 -- the largest Swiss event -- over a period of three days. The app offered information about the festival and featured a background localization allowing us to collect continuously the visitor position. With 56.000 app downloads and 28.000 user contributing 25M location updates in total, we obtained a large scale dataset. By aggregation of location points it captures complex crowd dynamics during the entire festival. In this paper we present the data collection for Zu ̈ri Fa ̈scht 2013 and best practises to acquire as many contributing users as possible for such an event. We show the potential of aggregating individual location data and visualising relevant parameters that can serve as tool for analysis and planning of program and perimeter design.},
