Summary In the classical continuous network design problem, the optimal capacity enhancements are determined by minimizing the total system cost under the budget constraint. Generally the equilibrium origin-destination travel costs for som O-D pairs may be increased after implementing the optimal capacity enhancements. This can lead to positive and/or negative results for network users. Therefore, the equity issue about the benefit gained from the continuous network design problem is raised. In this paper, we define a critical O-D travel cost ratio to quantify this equity issue. An efficient interval of this ratio can be identified by solving two bilevel programming models. Furthermore, another two bilevel programming models for the continuous network design problem are presented by incorporating this ratio into the model. A simulated annealing method has been used to test these four models for the Sioux Falls network.
