NATIONWIDE - 1997 # The mean annual VMT for the 5-axles or more fleet was 45,686 miles per truck. # Vehicles with the largest mean annual VMT in the fleet are doubles with 6-axles or more which have mean annual VMT of 59,488 miles per truck. # Vehicles with the smallest mean annual VMT in the fleet are triples with 15,469 miles per truck. # 3-S2s have an mean annual VMT of 58,735 miles per truck. 4-S1/S2s have an mean annual VMT of 61,676 miles per truck. Tridem axle semitrailers have an mean annual VMT of 56,374 miles per truck. CHANGES BETWEEN 1992 AND 1997 # The mean annual VMT for the 5-axles or more fleet experienced a 17% decrease of 18,314 miles from 64,000 miles/truck in 1992 to 45,686 miles/truck in 1997. # The mean annual VMT increased for truck+trailer with 5-axles, tridem axle semitrailers. # The mean annual VMT for 4S1/S2 did not change. # The mean annual VMT for triples appears to have decreased. However, given that only a small sample of triples were surveyed (178 in 1997 and 38 in 1992), this may be a statistical anomaly. NATIONWIDE - 1997 8.3 Annual VMT by Major Truck Configuration by Body Type # Vans have the largest mean annual VMT (80,000 miles/truck). Tank trucks for liquid or gases have the next largest mean annual VMT (54,000 miles/truck), and tank trucks hauling bulk goods has a slightly lower mean VMT (49,000 miles/truck). Dump trucks, auto transporters, and grain bodies have low mean VMT (
CHANGES BETWEEN 1992 AND 1997 Figure 8.3-1 compares, for 1987, 1992 and 1997, the mean annual VMT for particular body type/truck configurations. Figure 8.3-2 compares regionally the mean VMT for 3-S2s for selected body types. # The mean annual VMT for most body types did not vary significantly between the years. # 3-S2 Drop frame vans and 2-S1-2 basic enclosed vans have changed dramatically over the 3 periods. This may be an issue with changing definitions on the survey form. # Several body types experienced a decrease in their mean VMT, 3-S2 basic enclosed van, 3-S2 drop frame van, 3-S2 basic platform, and 3-S2 liquid/gas tank. 85
