- Abstract
- (en) Multi-Modal freight models are traditionally built following the well known "four steps model" in which generation, distribution, modal-split and assignment are seen as separated modules. An alternative approach, now implemented in some software, is to represent the multi-modal network by means of a "mono-modal" one, in which each particular transport operation (loading or unloading operation, transhipments ...) is represented by a dedicated "virtual link", that represents a specific operation in the transportation chain. This approach, promoted by several authors, often referenced to as "super networks" or "virtual networks", is proven to give interesting results, but has the drawback to generate much larger networks than the pure geographic representation of the studied area. It has also some kind of "hidden trap", linked to transport distances, that will be presented in this paper and that can only be solved using appropriate assignment techniques. This paper presents some res
