Considering the fact that today the most cost-effective way of shipment is sea transport, significant increase in the number of containers is expected. Therefore, the need for increased efficiency and security at the terminal arises. For that reason, new information systems for terminal management are introduced. Main objective of informational systems is supplying business systems with information that is needed for their further operations. One of the most widely used operating system is considered to be the NAVIS system. That system is relatively new, and allows complete information backup for all components at the container terminal. Process flow and all procedures that precede the arrival of the ship at the terminal and the acceptance of the cargo, must follow the decisions that are made for the work in the new terminal operating system.Considering the fact that Rijeka traffic route is of strategic interest for Croatia, and beyond, the role of strengthening the hinterland has the project of modernization and building new container terminal. Likewise, railroad is also of huge strategic interest for Croatia, which will boost the competitiveness of the port itself, thereby becoming the gateway to Europe.
