The free circulation of goods has led to a significant increase in intra-European commercial exchanges, notably in the centre of the European Union. This concentration has led to an imbalance with the congestion of the great road axes of European on the one hand, and the pushing aside of the peripheral regions, such as the Atlantic Area, on the other hand. In this context, SSSAA proposes to create solutions encouraging cabotage among the regions of the Atlantic Area, through the creation of new lines for navigation and through energising the existing lines.
