TABLE ES-1 1992 U.S. COMMERCIAL FREIGHT TRUCK FLEET HIGHLIGHTS (Trucks with 5-axles or more, unless noted otherwise) 7 5-Axle Tractor Semitrailer - Most common freight hauling truck - 22% of total truck fleet 1 - 80% of trucks with 5-axles or more - 13% growth in number of trucks between 1992/1997. 7 Truck + trailers [straight trucks pulling a trailer(s)] - 4% of total truck fleet 1 - Little change from 1992 or 1987. 7 Tractor-semitrailers with tridem axle trailers (2-S3, 3-S3, 4-S3) - 3% of total truck fleet 1 - 9% of trucks with 5-axles or more - 33% growth in the number of trucks between 1997/1992. 7 STAA (2-axle tractor with 2-28' trailing units) trucks - 1% of total truck fleet 1 - Only 4% of trucks with 5-axles or more 7 Double (2 or 3-axle tractor with 2 trailing units with 3+ axles) trucks - 2% of total truck fleet 1 - 7% of trucks with 5-axles or more. - 29% growth in number of trucks between 1997/1992. 7 Triple (2 or 3-axle tractor with 3-28' trailing units) trucks - Less than 1% of total truck fleet 1 - Less than 1% of trucks with 5-axles or more. - 71% growth in number of trucks between 1997/1992 Regional Differences 7 Southern Gulf Region had a 27% increase in trucks with 5-axles or more versus the national average of a 15% increase between 1992/1997. personal trucks. 1 The data reflect the total commercial truck fleet including trucks with 5-axles or more, but excludes ES-7
TABLE ES-1 1992 U.S. COMMERCIAL FREIGHT TRUCK FLEET HIGHLIGHTS (Trucks with 5-axles or more, unless noted otherwise) 7 Northern Central Region contains the largest number of trucks with 5-axles or more with 37%. 7 Illinois, California, Texas, Florida, and Ohio account for 28% of trucks with 5-axles or more. Trailer Types 7 3-S2 Van is the preferred freight hauling truck configuration accounting for 50% of all trucks with 5-axles or more. 7 Van is the preferred trailer body type, used for 40% of all trucks with 5-axles or more—a 21% growth in the number of trailers with this body type was experienced between 1992 and 1997. 7 Platform is second most common trailer type with 20% of all trailers, but little change from 1992. Commodities Hauled 7 Top 7 carried commodities are: Processed Foods, Building Material, Mixed Cargo, Farm Products, Machinery, Paper, Primary Metal, and Logs, respectively [as measured by total fleet vehicle miles of travel (VMT)]. 7 STAA vehicles (2-S1-2) and triples predominately carry Mixed Cargo products (as measured by VMT). 7 Tridem axle semitrailers predominately carry Building materials and Machinery products (as measured by VMT). Trailer Width 7 102" trailer width continues to gain favor in all major trailer body types (e.g., 73% of 3-S2 Basic Enclosed Vans use 102"). 7 96" trailer width still less than 50% for several trailer body types on 3-S2s (platform, low boy, dump, pole or logging, auto transport, liquid tank, and dry tank).
