| 摘 要： | 首先给出了考虑环境污染因素的双层规划城市交通配流模型,上层要求系统总的出行时间和CO排放总量最小,下层是一个弹性需求的UE问题;并设计了一个平衡迭代算法,对所给模型进行了求解,从而能得到车辆在各路段上的最优行驶速度;最后给出了两个简单的算例,对该模型及相应的求解算法进行了验证.

| Abstract: | In this paper a bi-level programming model is proposed to describe the traffic assignment problem under environmental objective. The upper problem is to minimize the system travel cost and the total amount of CO produced by certai n vehicular velocity, while the lower one is a user equilibrium problem under el astic demand. The equilibrium iterative solution algorithm is represented so tha t the optimal vehicular velocity of the model is obtained. At last some simple n umerical results are given to illustrate the applications of the model. |
