  1. Preferred citation style for this presentation • Axhausen K.W.(2012) Swiss Mikrozensus and its lessons, presentation at the “National Travel Surveys in Transition: International Perspective”, 91st Annual Meeting of the Transportation Research Board, Washington, D.C., January 2012.

  2. Swiss Mikrozensus and its lessons KW Axhausen January 2012

  3. Acknowledgements • Federal Office of Statistics (Marc Gindraux) • Federal Office of Spatial Development (Kurt Infanger, Helmut Honermann, TimoOhnmacht) • IVT (Claude Weis, Alex Erath) • TransSol (Phillip Fröhlich) • Transoptima (MilenkoVrtic)

  4. Funding: Mikrozensus 2010 • Federal Office of Statistics • Federal Office of Spatial Development • As responsible body for the National Passenger Travel Demand Model (VISUM and VISEVA) • Add-ons bought by various Cantons and municipalities • Support by • Other federal offices • ETHs

  5. Format: Mikrozensus 2010 • Geocoded CATI (LINK) • Person-based interview • Stage-based interview • Car-based routes characterised by two waypoints • Add-on modules (LINK) • Day trips without overnight stays • Journeys with overnights stays • Attitude towards transport policy • Integrated – but independent – SPs (IVT) • Mode choice • Route/departure time choice

  6. Samples: Mikrozensus 2010 • Household-based interviews (59’971) • Person-based interview (62’868) • Stage-based interview (310’193 stages) • Individual motor traffic-routes characterised by two viapoints (> 3km) • Train routes based on digitalised train network and HAFAS • Independent SPs based on following-up recruitment question (IVT)

  7. Protocol: Mikrozensus 2010 • CATI with a series of call attempts (no incentive) (72% response rate) • Recruitment for SP: 50% recruitment rate • Written customised SPs within 12 days of interview (85% of recruited eligible) • 70% response rate to the mailed SP surveys

  8. Lessons of the Mikrozensus 2010 • CATI still works for Switzerland • Geocoding works for 97% of addresses and 93% of stops • Waypoints capture routes (96% of cases); 81% of transit stages • Collect the data for the non-chosen alternatives during the survey • Integrate the SR data collection for the choice modelling within the RP survey • •

  9. Possible ideas for Mikrozensus 2015 • Random sample of persons from the population register (inc.mobile phone) • Routing for cycle and walk stages • Improved routing of bus stages • Geocoding of “visiting friends and relatives via search in the phone book • GPS element
