| Abstract: | Ramp settlement is a key issue in design of urban expressway.Through analyzing ramp configuration,the paper investigated the road networks along urban expressways.The bi-level programming model was used to describe the problem.In this model,the upper part considered the transportation planner's perspective in order to design an optimal network structure and achieve systems optimization.The lower part of this model showed respect to the network users in order to attain the variable demand equilibrium.The upp... |
