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 combination
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.
