KEY: R = revised.
a Beginning
in 1998, the Federal Highway Administration (FHWA) used the Census Bureau's 1997 Vehicle Inventory and Use Survey (VIUS) for its baseline estimate of single-unit 2-axle
6-tire or more trucks. Prior to 1998,
the FHWA used the Census Bureau's 1992
Transportation Inventory and Use Survey
(TIUS) for its baseline estimates.
Therefore, post-1997 data may not be comparable to 1997 and earlier
years.
NOTES
In
1995, the U.S. Department of Transportation, Federal Highway Administration
revised its vehicle categories beginning with 1993 data to include passenger
cars, other 2-axle 4-tire vehicles, single-unit 2-axle 6-tire or more trucks,
and combination trucks. Single-unit 2-axle 6-tire or more trucks are on a
single frame with at least 2 axles and 6 tires. Pre-1993 data have been reassigned to the
most appropriate category.
