  1. National transport surveys – What can we learn from international comparisons? Patrick BONNEL Laboratoire d’Economie des Transports, Lyon, France Jimmy ARMOOGUM INRETS-DEST, Arcueil, France COST 355 WATCH, Berlin, November 25, 2005

  2. Objectives • National transport surveys are conducted periodically in some countries • What can we learn from international comparison for the next French National Transport Survey planned for 2007? • How comparable are surveys and data? Trip rate per day 4 , 5 4 3 , 5 3 2 , 5 2 1 , 5 Trip rate 1 0 , 5 0 CH D USA NO NL A GB F

  3. 12 countries • A: Austria • B: Belgium • DK: Denmark • FI: Finland • D: Germany • GB: Great Britain • N: Norway • E: Spain • S: Sweden • CH: Switzerland • US: USA • F: France

  4. Objectives of National Transport Surveys

  5. National Transport Surveys: content • Socio-demographic data • Daily mobility (1 to 7 days) • Long distance mobility (1 week to 6 month)

  6. Daily local mobility: trip definition + distance limit GB, E and CH

  7. Long distance: definition Denmark: no definition

  8. Survey periodicity

  9. Sampling base and survey unit

  10. Sampling • Random sample + geographical stratification (except DK, FI, N) + socio-demographics stratification (B, GB, E, F)

  11. Survey mode

  12. Daily local trip collection • Randomly predefined day: A, FI, D, GB, N, E, S, CH, US • Day of the week Randomly predefined: B • Uniform distribution over week days : DK, F • Duration: 1 day except GB: 1 week; E: 1 week day + 1 weekend day; F 1 week day + 2 weekend days • Trips collection by memory: DK, CH, E, F • memory jogger + a posteriori trips collection: FI, D, N, S, US • Self administered trips collection: A, B, GB

  13. Long-distance trip collection • 1 day: DK • 2 weeks: A • 4 weeks/1 month: B, FI, GB, N, S (100 to 300 km), US • 2 months: E, S (> 300km) • 3 months: D • 4 months: CH • 3 + 3 months: F Always by memory (except DK, F (next 3 months))

  14. Geolocation and geographical data collection • Origin+destination + distance: all countries except E • Origin+destination: E • Zoning : • Communal : A, GB, E, US, F • Geolocalisation without a priori zoning: • Real time codification: N, S, CH • a posteriori codification: B, DK, FI, D • GPS use or cellular phone: project in US, F

  15. Response rate, weighting, external control

  16. Cost, duration

  17. Conclusion • Objectives, definitions, methods are different for each country • Limited comparability during time within country and very problematic between countries • Harmonisation wishable, but… • National statistical data • Various sampling data base • Various definition • Various culture (survey mode) • For next French national transport survey • Use of CAPI system • GPS test • Work on continuous survey
