This paper presents a dynamic user equilibrium process in TRANSIMS. While TRANSIMS is characterized by an activity-based travel demand model, it can also be used as a trip-based model by using origin-destination trip data with departure patterns. The main foci of this paper are to investigate TRANSIMS’s dynamic traffic assignment characteristics and to evaluate its convergence property associated with its traffic assignment methods. In a test network, various postulated equilibrium process scenarios are experimented and their convergence properties are compared. Dynamic user equilibrium convergence properties obtained from day-to-day evolutional approach are compared in a highway work zone case. Various dynamic user equilibrium analyses provide intuitions on model convergence and travelers’ behavioral characteristics.
