The objective of this research project was to model the traffic performance networks in which travelers have heterogeneous preferences for aspects of their trip. In real networks, drivers make choices of which route to use based on many criteria including the travel time and the variability of travel time. This research project focused on developing equilibrium models that recognize the differences in preferences among travelers. The resulting model related the performance of links in a network to the equilibrium distribution of routes selected by drivers. The equilibrium method was based on an analytical approach that has applications to many transportation problems in which individuals make travel choices based on multiple criteria. The resulting approach has applications to systems of car traffic and transit use, as well as to the development of advanced traveler information systems that account for diverse travel preferences among users.
