We present a mixed integer linear program for the rapid transit network design problem with static modal competition.Previous discrete formulations cannot handle modal competition for realistic size instances because of the complexity of modeling alternatives for each flow in the network.We overcome this difficulty by exploiting a pre-assigned topological configuration.We discuss relevant goals of rapid transit planning, and we propose a multi-objective model conducive to a post-optimization analysis for effectiveness, efficiency, and equity concerns. A case study carried out for a metro proposal in Concepción, Chile, shows the suitability of the method.
