¹ “Vacation” includes rest and relaxation.

NOTE: The 2001 National Household Travel Survey defined a trip as each time a person went from one address to another. “Commute” trips were defined as those trips made for the purpose of going to or returning from work. However, given the definition of a trip, those reported as commuting trips were not necessarily anchored by the home or workplace (for return commutes). Therefore, care should be taken in analyzing to/from work trips, recognizing that the distance for these trips is often, but not always, the distance from home to work. Excluded from work-related business trips are trips made by people who are directly providing the transportation of passengers or goods, such as bus or truck drivers, delivery persons, etc.
