Abstract: Trucks of various sizes and performance capabilities have different effects on the quality of traffic operations. Thus, introducing new truck types into the traffic stream to partially or completely replace other vehicle types can potentially result in changes in traffic operational quality and in highway capacity. The objective of this study was to develop a methodology for estimating the changes in traffic operational performance as a function of changes in the U.S. Federal policy for vehicle size and weight. These impacts can he estimated in terms of changes in travel delay experienced by all vehicles in the US highway network, and their associated costs. The method described in this paper was implemented in a computerised model (DELAY$). The computerised model has the capability to provide estimates of changes in total annual vehicle delay and associated costs.
