TY - CONF T1 - Use of mobile phone data to estimate visitors mobility flows T2 - Proceedings of MoKMaSD Y1 - 2014 A1 - Lorenzo Gabrielli A1 - Barbara Furletti A1 - Fosca Giannotti A1 - Mirco Nanni A1 - S Rinzivillo AB - Big Data originating from the digital breadcrumbs of human activities, sensed as by-product of the technologies that we use for our daily activities, allows us to observe the individual and collective behavior of people at an unprecedented detail. Many dimensions of our social life have big data “proxies”, such as the mo- bile 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 JF - Proceedings of MoKMaSD UR - http://www.di.unipi.it/mokmasd/symposium-2014/preproceedings/GabrielliEtAl-mokmasd2014.pdf ER -
