Abstract
This study introduces a link-based traffic assignment and equilibrium model for multi-modal networks considering congestion effects on travel times. To seamlessly enable the mode switch at any step of the journey, we employ an intervention control modelling technique that utilizes a multi-layer network wherein each layer corresponds to a feasible mode choice. The approach also enables us to prescribe node-dependent mode switching costs. The solution technique relies on dynamic programming and allows us to implicitly consider all possible route and mode choice combinations without enumerating all of them explicitly. This model can be used to design, analyze, and operate transportation systems that include multiple modes such as a variety of sustainable options.
