Today, we can talk about a European port system, as each country's foreign trade entry and exit points do not necessarily pass through a national port. In this regard, Europe's main entry and exit points are located in the major northern ports, particularly Rotterdam and Antwerp. However, we must now also take into account the extraordinary growth of foreign ports in the south, particularly in the container sector. The study of ports is not interesting when we consider the scale of traffic diversions and the importance of road transport for our port services.
