Abstract
One of the main problems in the freight transport is the congestion that can occur in multi-modal nodes and how this may affect the use that the load makes the entire transport system. Aggregate transport models take into account congestion in a simplified way, which may introduce bias in the estimation. Discrete events simulation provides a better tool for explaining the mechanisms that lead to congestion. This paper presents a comparison between an aggregate transport model and a model of discrete events that takes into account the delays caused by congestion at the nodes and how they affect modal choice. The goal is to assess the bias caused by the aggregated approach and whether it compromises the validity of the modal split estimation.
