Personal Travel: 1977, 1983, 1990, and 1995

Note: The Nationwide Personal Transportation Survey (NPTS) was first conducted in 1969, and then again in 1977, 1983, 1990, and 1995. Numerous methodological improvements in the NPTS make exact comparisons across time difficult, but travel behavior for these two points in time are adequately reflected in the survey data.
