7.0 <strong>Analysis</strong> <strong>of</strong> Weights, Dimensions, <strong>and</strong> Operating<br />
Characteristics <strong>for</strong> <strong>the</strong> 5-Axles or More Fleet<br />
7.1 <strong>Analysis</strong> Structure<br />
More than 93% <strong>of</strong> <strong>the</strong> 1997 5-axles or more fleet is accounted <strong>for</strong> by <strong>the</strong> combination <strong>of</strong> <strong>the</strong> 4<br />
specific truck configurations <strong>and</strong> <strong>the</strong> 13 specific body types listed below:<br />
FOUR SPECIFIC CONFIGURATIONS<br />
# <strong>the</strong> 3 + 2 truck + trailer (4.39%)<br />
# <strong>the</strong> 3-S2 tractor-semitrailer (75.11%)<br />
# <strong>the</strong> 3-S3 tractor-semitrailer (9.60%)<br />
# <strong>the</strong> 2-S1-2 STAA tractor + double trailer combination (3.95%).<br />
THIRTEEN SPECIFIC BODY TYPES<br />
# low boy<br />
# basic plat<strong>for</strong>m<br />
# livestock truck<br />
# insulated non-refrigerated van<br />
# insulated refrigerated van<br />
# drop frame van<br />
# basic enclosed van<br />
# pole <strong>and</strong> logging truck<br />
# automobile transporter<br />
# grain body<br />
# dump truck<br />
# tank truck <strong>for</strong> liquids or gases<br />
# tank truck <strong>for</strong> dry bulk.<br />
Various combinations <strong>of</strong> configuration <strong>and</strong> body type (e.g., <strong>the</strong> 3-S2 refrigerated van) were<br />
chosen <strong>for</strong> analysis based on <strong>the</strong>ir occurrence in <strong>the</strong> truck fleet. The most prevalent<br />
configuration/body types in <strong>the</strong> truck fleet were analyzed in terms <strong>of</strong> <strong>the</strong>ir national operational<br />
characteristics <strong>for</strong> both 1997 <strong>and</strong> 1992. Eight vehicle characteristics were <strong>of</strong> interest:<br />
# empty (tare) weight<br />
# average gross weight<br />
# maximum gross weight<br />
# external width <strong>of</strong> trailer<br />
# overall length<br />
# annual vehicle miles <strong>of</strong> travel (VMT)<br />
# base <strong>of</strong> operation<br />
# range <strong>of</strong> operation—% <strong>of</strong> VMT operating in different lengths <strong>of</strong> haul<br />
