This work is about the modelling of a logistic corridor in order to understand how a logistic system is structured and organised. An agent-based approach and dynamic graphs are used to integrate spatial constraints and functional rules of such a complex system which can be studied with a multi-scale point of view. An implementation on a simulation platform provides first results on a corridor of the Northern European range: the Seine axis. It is shown that the model can answer to the problematic but provides also features of decision support of spatial planning.
