The work presented here must be viewed as only a first step toward better understanding of the interaction of various vehicle classes in determining the performance of transportation facilities. Results have been presented of the empirical development and calibration of link performance functions that capture the dependence of travel time on the respective volumes of passenger cars and trucks sharing the physical right-of-way. These functions are intended for use in network equilibrium studies requiring the assignment of explicit car and truck flows, and therefore involving asymmetric interactions between these vehicle classes (or equivalently between links). This problem arises, for example, in the context of the evaluation of truck-related highway improvements, which is a problem of current interest to highway agencies.
