提出了一种求解行程时间不确定的动态系统最优交通分配问题的方法。将具有两个平行链路的网络中的DSO分配问题表示为一个随机控制问题，给出了分配问题的最优性条件。然后，我们证明了最优性条件可以等价地表示为广义互补问题（GCP）的动力系统。在此基础上，我们提供了一个有效的算法来解决随机控制问题。
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.
