摘要：	For nationwide household surveys, France and the United States traditionally give a different answer to this question: Is it necessary to collect data on daily mobility and long-distance travel in the same survey? France has dealt with both topics in the same big and infrequent surveys (1981-1982 and 1993-1994). Because of the difference in the frequency of trips according to their length, different instruments are clearly needed. For instance, in the last national survey conducted in France, the following were used: an interview concerning trips made the previous day and during the previous weekend and a 7-day car diary for daily mobility; and an interview about the previous 3 months plus a self-administered questionnaire for journeys, where at least one destination was more than 80-km great circle distance from the place of residence. This standard threshold has to be discussed. The main advantages are: the general description of the household, of its members and of their vehicles has only once to be done; and the information collected can be cross-checked (for instance, the mileage is controlled with the odometer in the car diary, which allows the discussion of the perception of trip distance). The main drawback is clearly that the survey is too long (1.5 h on average), which means that only one person can be interviewed for daily mobility and one person (the same one in only half of the surveyed households) for long-distance travel. The analysis of overall mobility was first conducted by clustering trips according to their characteristics (mode, purpose, day of the week, and duration). Some of the classes are typical of local mobility (school trips by public transport) or of long distance (leisure journeys by air), but others are mixed (professional trips by train or car). A second clustering analysis is implemented on individuals according to the distribution of their trips in these different classes.
