TELCO GEOBIGDATA FOR THE ANALYSIS OF PRESENCES AND MOVEMENTS: THE 2023 “ADUNATA DEGLI ALPINI” IN UDINE

Abstract. The GEO Big Data phenomenon has become a central topic in the innovation debate. Understanding the presence and movement of individuals within a geographical area is crucial in many fields: urban planning, transport systems, emergencies, tourism, events, … In the last few years a new source of information to reconstruct the dynamics of such complex systems are the data acquired from cellular phone that trace presences and movements with high precision. For privacy issues the data are sold geographically aggregated by TELCO companies. The study of the dynamics of incoming and outgoing, number of trips, number of days and nights spent, number of unique visitors, country of residence and origin, main destination, secondary destination, transit and repeated visits have been analysed for the annual gathering of the ALPINI held in May 2023 in Udine. This work demonstrates how accurate this information is and how it can be used, in addition to analysing the previous edition, to plan locations, logistics, and agendas for future editions.
