Abstract

Multi-Modal freight models are traditionally built following the well known "fours steps model" in which generation, distribution, modal-split and assignment are seen as separated modules. An alternative approach, implemented in some softwares, is to represent the multi-modal network by means of a mono-modal one, representing each particular transport operation (loading or unloading,operation, transshipments, ...) by a dedicated "virtual link". This approach is proven to give interesting results, but as the drawback to generate much larger networks as their geographic representation. These huge networks (often larger than several houndreds of thousands links) made it difficult to implement loop-based equilibrium assignement techniques. The increasing computation power of recent hardware make it now much more easy to test several alternative assignment techniques. This paper presents some results obtained on a large multi-modal network, using different equilibrium assignment algorithms.
