Note: All tables reporting totals could include some unreported characteristics.
Note that only the 1990 data have been adjusted to make them more comparable with the 1995 and 2001 data.
Thus, there are limits on the conclusions that can be drawn in comparing travel with earlier survey years. The
adjustments to 1990 data affect only person trips, vehicle trips, person miles of travel (PMT) and vehicle miles
of travel (VMT).
The 1969 survey included only automobiles, station wagons, vans, and minibuses as household vehicles.
