Several Federal Government agencies require estimates of vehicle miles of travel (VMT) by interstate commercial trucks. These estimates are essential in determining accident exposure and accident rates for these trucks, and in determining highway investment needs and the allocation of highway costs. VMT estimates are currently based on various nationwide transportation surveys and/or data sources using various estimation procedures do not provide consistent estimates. A summary of evaluation results of these data sources and estimation procedures is presented in this paper. 4 refs., 1 tab.
