This paper addresses the problems faced by a central controller seeking to optimize overall network performance through the provision of real-time routing information to equipped motorists, taking into account different user classes in terms of information availability information supply strategy, and response behavior. Four classes of users are incorporated in the formulation. Given time-dependent O-D trip desires for users in each of these four classes, the formulation seeks a time-dependent traffic assignment which provides the number of vehicles of each class on the network links and paths. A simulation- based algorithm is presented, extending previous work by the authors for single-class time-dependent assignment. The DYNASMART simulation model is used to evaluate any particular path assignment pattern and provide the information necessary to guide the search to the solution satisfying the desired conditions.
