| 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 certain vehicular velocity, while the lower one is a user equilibrium problem under elastic demand. The equilibrium iterative solution algorithm is represented so that the optimal vehicular velocity of the model is obtained. At last some simple numerical results are given to illustrate the applications of the model. |
