Note: For survey references, see table 1. Sources for national traffic volume: ICAO statistics for scheduled and charter air travel. All other modes from national statistics: Australia: Australian Bureau of Statistics (various years); Austria: not applicable since survey excludes travel on weekends; France: INSEE (1986, 1995); Japan: not applicable since survey includes trip length only for automobiles; Netherlands: Statistics Netherlands (1998); Norway: Statistics Norway (various years); Singapore: independent statistics not available; Switzerland: Bundesamt für Statistik (1997); Great Britain: Department of Transport (various years), United States: U.S. Department of Transportation (several years), Davis (1998); West Germany: Deutsches Institut für Wirtschaftsforschung (1987, 1996).
HH: household, PKMT: passenger-kilometers traveled. The response rate is defined as the number of complete household interviews to the number of
eligible households
