  1. NTTS 2017 Travelling SIM and Trips: an approach to make mobile phone data usable in tourism statistics Barbara Dattilo (*) dattilo@istat.it Mariangela Sabato (*)sabato@istat.it (* ) ISTAT -Italian National Institute of Statistics Session 6A: Mobile phone data for mobility statistics - Using mobile phone data for statistics on tourism and transport 14th March 2017

  2. The ISTAT PROJECTExperimentation on the use of mobile phone data for statistics on tourism demand A project work: • launched in 2015 within Trips and Holidays Survey (THS); • included in Italian National Statistical Program; • compliant with ISTAT roadmapfor the Adoption of Big Data for Official Statistics (2013); • involved into the framework of the definition of nationalagreements with MNOs about mobile phone data provision for tourism surveys (ongoing) • Short and medium term outcomes • methodology for the use of mobile phone data aimed at the construction of calibrators to be applied to the CDRs / DDRs • Long-term outcomes • production of indicators on domestic tourism at territorial and temporal level more detailed, than those that can be estimated by the current Trips and Holidays Survey (THS); Session 6A: Mobile phone data for mobility statistics – Using mobile phone data for statistics on tourism and transport14th March 2017

  3. MOBILE PHONE DATA FOR TOURISM STATISTICSChallenges • General issues on mobile phone data usage • privacy and regulatory • technology • business model and agreement with MNO’s • communication by NSI to the general public • Methodological issues on mobile phone data usage in tourism field • International definitions (target population) • Coverage of CDRs/DDRs Session 6A: Mobile phone data for mobility statistics – Using mobile phone data for statistics on tourism and transport14th March 2017

  4. The ISTAT PROJECTHow mobile phone data can be usable in tourism statistics to obtain information about tourism flows? • QUALITY: How to treat the selectivity bias? • A feasible approach: integration of two sources - official statistical system (THS) and mobile phone traffic (CDRs/DDRs) Session 6A: Mobile phone data for mobility statistics – Using mobile phone data for statistics on tourism and transport14th March 2017

  5. METHODOLOGY: Mobile phoneModule TRIPS TRAVELLING SIM • «Metadata»: use/availability mobile phoneduring a trip, use pattern, habits of usage, etc. • assessment of the reliability and the level of CDRs / DDRs coverage • construction of calibrators to be applied to the mobile phone data • how much the mobile phone is used during the trip; • howthe mobile phone is used during the trip (calls, SMS / MMS, internet connection); • numberof “travelling” SIM; • typeof SIM owners (participants/non participant in the trip, companies, etc.). CONDITIO SINE QUA NON: having done preliminary operations of "normalization", regarding the usual environment in temporal and spatial terms Session 6A: Mobile phone data for mobility statistics – Using mobile phone data for statistics on tourism and transport14th March 2017

  10. RECOMMENDATIONS AND NEXT STEPS • RECOMMENDATIONS: this is one of the possible approaches to verify the feasibility of including mobile data in the official system of tourism statistics. • NEXT STEPS • VALIDATIONof the methodology on a test dataset provided by one or more MNOs on a large territorial area (at least regional) • PERIODICITY of Mobile phone Module: consolidated and stable results  i.e. every 5 years? • CONDITIO SINE QUA NON • OVERCOMING METHODOLOGICAL OBSTACLES (e.g. definition of the observation period of the “phone events", also functional to the usual environment delimitation of the mobile phone subscriber); • REACHING FORMAL AGREEMENTS WITH MNO’S FOR DATA PROVISION • defining which types of data MNOs will provide (CDRs and/or DDRs?) • defining which variables will be available • ensuring temporal continuity and territorial coverage of data provision Session 6A: Mobile phone data for mobility statistics – Using mobile phone data for statistics on tourism and transport14th March 2017
