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.
Numbers may differ slightly from previous year's metric tables
because a higher precision conversion factor was used.
