Résumé / Abstract
This paper reports method used to correct non-response for daily mobility in the French national transportation surveys. A two-stage technique was used for unit non-response: 1) post stratification according to the households' characteristics related to response behavior; and 2) correction for sampling error by calibration on margins. Imputation procedures (e.g., deductive, regression based, ho-deck) were also used to correct item non-response. These methods maintained the consistent relationships among the main variables describing trips. The paper also addresses how the specific circumstances of this case (e.g., sample drawn from the census, no computer assistance during the interviews) led to the choice of methods.
