The proposal includes a gravitational model that deforms the surface of the city based on the intensity of the activity in different zones. The information is extracted from geolocated tweets ( n = 1 . 48 × 1 0 6 ). Furthermore, this activity affects how people move in a city. The path a user follows is calculated using the geolocation of the tweets that he or she publishes along the day. Several models are evaluated and compared using the Hausdorf’s distance ( d H ). The combination of gravitational potential with attraction to the destination points provides the best results, with d H = 1176 against the Manhattan ( d H = 1203 ) or the geodesic ( d H = 1417 ) alternatives. Finally, the analysis is repeated with the data segmented by gender (n=2,826 paths, men=1,910, women=916). The results validate (p=0.000334) the studies that affirm that men travel longer di...
