This study investigates a travelers’ day-to-day route flow dynamic model under a predefined market penetration of advanced traveler information system (ATIS). It is assumed that some travelers equipped with ATIS will follow the deterministic user equilibrium route choice behavior due to the complete traffic information provided by ATIS, while the other travelers unequipped with ATIS will follow the stochastic user equilibrium route choice behavior. The interaction between these two groups of travelers will result in a mixed equilibrium state. The authors first propose a discrete day-to-day route flow adjustment process for this mixed equilibrium behavior by specifying the travelers’ route adjustment principle and adjustment ratio. The convergence of proposed day-to-day flow dynamic model to the mixed equilibrium state is rigorously demonstrated under certain assumptions on route adjustment principle and adjustment ratio. In addition, without affecting the convergence of proposed day-to-day flow dynamic model, the assumption on the adjustment ratio is further relaxed, thus making the proposed model more appealing in practice. Finally, numerical experiments are conducted to illustrate the performance of proposed day-to-day flow dynamic model.
