Vehicle Inventory and Use Survey
Until 2002, the U.S. Census Bureau conducted the Vehicle Inventory and Use Survey
to collect data on the physical characteristics and activity of U.S. trucks every five
years. The survey is a sample of private and commercial trucks that were registered in the U.S.
as of July of the survey year. The survey excludes automobiles, motorcycles, government-owed
vehicles, ambulances, buses, motor homes and nonroad equipment. For MOVES, VIUS
provides information to characterize trucks by SourceType and to estimate age distributions.
Draft MOVES2009 uses data from both the 1997 and 20022
surveys. Before 1997, VIUS was
known as TIUS (Truck Inventory and Use Survey). To populate the 1990 base year, we used data
from the 1992 TIUS.3
