Multimodal Feeder Network Design Problem: Ant Colony Optimization Approach

Significant service performance capabilities of high-capacity mass transit make it a remarkable part of any large metropolitan transportation system. Unfortunately it is not feasible to provide citywide direct access to high-capacity transit. Other modes of transit are used as feeders to collect and deliver passengers to high-capacity mass transit. By using feeder lines the possibility of use of high-capacity mass transit increases because the travel demand for a more extended area can be satisfied. In this research, multiple modes with various capacities and performances are used in the feeder network design based on the minimization of user, operator, and social costs. Other approaches have only used one mode (usually bus) for designing the feeder network.
