Many dimensions of our social life have big data “proxies”, such as the mobile calls data for mobility. In this paper we investigate to what extent data coming from mobile operators could be a support in producing reliable and timely estimates of intra-city mobility flows. The idea is to define an estimation method based on calling data to characterize the mobility habits of visitors at the level of a single municipality.1 aGabrielli, Lorenzo1 aFurletti, Barbara1 aGiannotti, Fosca1 aNanni, Mirco1 aRinzivillo, S  uhttp://link.springer.com/chapter/10.1007%2F978-3-319-15201-1_14
