This paper copes with freight transport network design, particularly in the selection of the most feasible set of infrastructure projects. The problem involves investment planning, which can be transformed to a combinatorial optimisation problem of identifying and selecting the best set of feasible actions from a number of possible actions. A mathematical model is developed within the framework of bi-level programming problem, where a multimodal multi-user assignment technique is incorporated within the lower level problem and the combination of actions for capacity expansion is optimised using genetic algorithm-based procedures in the upper level problem. Model application to the actual freight transport network in Indonesia reveals that the model can adequately select the best combination of actions for designing the optimal multimodal freight network.
