Abstract

This paper presents a method for solving a dynamic system optimal (DSO) traffic assignment problem with uncertain travel time. Formulating the DSO assignment in a network with two parallel links as a stochastic control problem, we derive the optimality conditions of the assignment problem. We then show that the optimality conditions can be equivalently stated as a dynamical system of generalized complementarity problems (GCP). Based on this reformulation, we provide an efficient algorithm for solving the stochastic control problem.
