http://www.disit.org considerazioni
• Dati telefonici:
– Catturano sia residenti che turisti senza una forte distinzione
– Cons: Non permettano di tracciare matrici origine destinazione
– Cons: Sono ad una risoluzione troppo bassa: 15 minuti → 6 ore
– Pros: valutano anche fuori dall’area urbana
• Dati Firenze WiFi:
– Catturano principalmente i turisti e movimenti in strada
– Permettono di fare matrici OD solo se la rete e’ ben instrumentata
– Forte correlazione con dati delle reti cellulari negli orari centrali
– Cons: non lavorano fuori dall’area ubana
