The report presents population estimates derived from the 1987 Truck Inventory and Use Survey (TIUS). The TIUS is conducted every five years by the Bureau of the Census as part of the Census of Transportation. Trucks of all weight classes are randomly selected from each state's motor vehicle registration files, and owners of selected trucks respond to mailed survey forms. The owners characterize their trucks in terms of the typical configuration and use over the previous year. TIUS data may be used to calculate national population estimates of the number of trucks and their annual travel. The population estimates presented here pertain to medium- and heavy-duty trucks, those with a GVWR exceeding 10,000 pounds. Trucks registered in FHWA field region 5, which includes six midwestern states, are compared with trucks in the nation as a whole. Trucks registered in Region 5 comprise 21.4% of the large trucks in the country and account for nearly one-quarter of all travel by large trucks. The report characterizes trucks in Region 5 and the nation in terms of power unit type, cargo body style, average and maximum gross weight, carrier type, area of operation, out-of-state travel, major use, and principal product carried. It was found that Region 5 large truck registrations include proportionately more truck-tractors than large trucks nationally and that Region 5 tractors average more miles of annual travel than tractors in the nation as a whole.
