5. 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. 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. 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. 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. 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 9 Possible ideas for Mikrozensus 2015
