Description of target statistical outputs Classifying and Measuring urban population Producing an Origin Destination matrix at municipal level Defining a method of integrating administrative data sources and mobile data Description of target statistical outputs

Classifying municipality population (Users) A person is Resident in an area A when his/her home is inside A. Therefore the mobility tends to be from and towards his/her home. A person is a Commuter between an area B and an area A if his/her home is in B while the work/school place is in A. Therefore the daily mobility of this person is mainly between B and A. A person is a Dynamic Resident between an area A and an area B if his/her home is in A while the work/school place is in B. A Dynamic Resident represents a sort of “opposite” of the Commuter. A person is a Visitor in an area A if his/her home and work/school places are outside A, and the presence inside the area is limited to a certain period of time that can allow him/her to perform some activities in A. B A B A A B Description of national ongoing/intended data processing

Passersby We distinguish between Visitors and the subclass Passersby (people making a single call) It is a heuristic method which allows for the exclusion of highways or airports in some cases and characterizes a different kind of visit 1 single call Multiple calls Description of target statistical outputs

Measuring urban population Measuring urban population, aggregating: Ranking: Resident, Commuter, Dynamic Resident, and Visitor Municipality level Observed period (between 9 January and 12 February) Description of target statistical outputs

Producing O/D Matrices Considering the “home” location of the user we can compute the O/D Matrix representing people’s movement on a particular day or period. Description of target statistical outputs

Integrating administrative data sources and mobile data The first results computed on the CDR data show a good correlation between the administrative data provided by ISTAT and CDR. This is a prerequisite for evaluating the use of mobile data to estimate particular statistical aggregate making use also of administrative data. For instance, at ISTAT it is possible to estimate (making use of the Census or administrative data) the no-resident working or studying population in a municipality. The population of commuters and dynamic residents can be estimated by using CDRs . This population can be used in the total populations in order to obtaine the sub-aggregate.
