- 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". This approach is proven to give interesting results, but has the drawback to generate much larger networks than the pure geographic representation of the studied area. These huge networks (often larger than several hundreds of thousands links) made it difficult to implement iterative equilibrium assignment techniques, but the increasing computation power of recent hardware makes it now much more easy to handle and test several alternative assignment techniques on large networks. This paper presents some results obtained on a
