Abstract

In the aim for a more sustainable transport system, governments try to stimulate multimodal trip making by facilitating smooth transfers between modes. The assessment of related multimodal policy measures requires transport models that are capable of handling the complex nature of multimodality. This complexity sets requirements for adequate modeling of multimodal travel behavior and can be categorized into three classes related to the range and combinatorial complexity of the choice set, the mathematical complexity of the choice model, and the complexity in demand-supply interactions. Classical modeling approaches typically fail to meet these requirements while state-of-the-practice approaches only partly fulfill these. Hence, the underlying hypothesis of this study is that application of such models in network design implies an ill decision-making process. These modelling approaches, as well as the promising state-of-the-research super-network approach, are therefore conceptually compared to each other. Requirements for multimodality are constructed, and all three models are tested regarding how these requirements can be met. The findings of this comparison are supported by realistic examples in the real-world transport network of the Amsterdam Metropolitan Area. It is shown that theoretical shortcomings of classical and state-of-the-practice approach indeed result in implausible predictions of multimodal travel behavior. The flexibility of the super-network approach, on the other hand, is well capable of describing the expected impact of supply changes on travel behavior in most situations. Hereby, this study illustrates the urgency for applying sound multimodal modeling approaches in network design studies.
