ANALYSIS OF THE TRUCK INVENTORY AND USE SURVEY (TIUS) FROM THE TRUCK SIZE AND WEIGHT PERSPECTIVE FOR TRUCKS WITH FOUR-AXLES OR LESS. U.S. DEPARTMENT OF TRANSPORTATION COMPREHENSIVE TRUCK SIZE AND WEIGHT STUDY REPORT NO. 6, ACTIVITY I: TASK B IDENTIFY MARKET SEGMENTS - COMPETITIVE AND NONCOMPETITIVE TIUS DATA COMPONENT

This report, as part of the U.S. Department of Transportation (DOT) Comprehensive Truck Size and Weight (TS&W) Study, provides factual information and analysis of the U.S. freight hauling truck fleet, and is based on the Truck Inventory and Use Survey (TIUS) data bases from 1992 and 1987. The U.S. Bureau of the Census collects truck data every five years with 1992 being the latest data available. The TIUS can be used to help understand the U.S. truck fleet makeup, size, uses, location, and type of commodities hauled at the national, regional, and local levels. This information will be used to present a picture of the U.S. truck fleet and its uses as well as to evaluate the potential national/regional TS&W policy options. The TIUS provides data on the physical and operational characteristics of the U.S. truck fleet. The survey sample is drawn from each state's registration records. The sample contains privately- and commercially-owned trucks, as well as trucks used for personal transportation and freight hauling. This report on the 4-axles or less truck fleet compliments an earlier U.S. DOT TS&W Study (Report #2) of the 5-axles or more commercial freight hauling fleet. Specific 4-axles or less truck types analyzed include: single unit straight truck, single unit truck with trailer, and tractor with semitrailer.
