Change over time lacks: Monitoring of individual change in behaviour, Narrative of a history of mobility. For both of these aspects, biographic surveys can bring new field data. Biographiesfor sustainable mobility

  3. Example of cross-section trend France

  4. Follow-up of panels Biography: asking persons how they have travelled for their lifetime Why? Understanding how and when changes have occurred Relating present mobility patterns to past practices Defining what a habit is Monitoring of individual change in behaviour

  5. Example of longitudinal analysis(car rental) • 29% of renters in year t rent again in t+1 • 51% of renters in both year t and year t+1rent again in year t+2 • And so on • For a minority of renters, renting is a sustained habit • Multi-renters rent more often next year

  6. Historical sources: describe the history of transport technology and the economic and social changes involved Biography: asking people which mode they travelled in years as early as 1930 Reconstructed past modal shifts, ajusted to existing points in time given by transport surveys according to location type, occupation, gender and age groups. Mobility transition from walking as the traditional main mode of daily travel to automobile, which occurred in France in the 1950s, before the first transport survey. Writing of mobility history

  7. Example of historical sources Per day Cumulated traffic intensity on national roads, 1894-1965Sabine Barles, LTMU, PIE Seminar, 2004

  8. The mobility transition distances, France, Grübler

  9. Evolution of world mobility

  10. North America km/person/day car air walking

  16. First version Tested in spring 2005 with a paper questionnaire Too complicated Added burden to interviewees at the end of the first visit New version To be tested with CAPI in spring 2006 Inspired from the former INSEE survey Based on a chronological grid where all events are recorded Proposal for next French NHTS 2007

  17. Place of residence by municipality Number of motor vehicles (two- and four-wheelers) available in household Main activity(school or work) and place of activity by municipality Usual transport mode for commuting, or overall if no commuting occurs. Four elements

  21. Questionnaire (2)

  22. Questionnaire (3)

  23. Questionnaire (4)

  24. List of usual transport modes

  25. List of activities

  26. Grid to be filled Until 90 years old

  27. Example of filled grid

  28. Questions about father and mother
