ABSTRACT
Any attempt to prove that SSS significantly contributes to the development of a greener multimodal freight transport system should be accompanied by an accurate estimation of the related cost of transport shifting. In this chapter, the reader may see an example of determining this cost. In particular, the case study presented examines the possibility of using maritime shipping routes instead of road transport across a 250-km distance in Greece. The alternative of a seaborne connection between Patras and West Attica via the Corinth Canal is indeed a fitting case study, since in order to establish and evaluate the potential competitiveness of SSS as compared to using the road network it would be necessary to take into account private costs and revenue and also external factors.
