Maritime traffic is essential for global trade, as around 80% of the world's trade is conducted throught sea traffic. Seaports have become a crucial element in the global supply chain, with the largest share of goods in international exchange reaching end customers through them. In ports and trade exchanges, the container plays a key role as it is the most important unit in the movement of goods. However, the use of containers for traffic has introduced significant safety risks. In container maritime traffic, accidents often occur due to improper handling, loading, and stacking of containers. The way containers are managed on vessels significantly impacts the safety of the crew, dock workers, and the vessel itself. Key components in ensuring high-quality service include container tracking and additional services in container traffic. This thesis highlights the importance of advanced information technologies and tracking systems in container ports and their significance on a global level. These systems are essential for keeping track of container locations because today’s ports handle a large number of containers stored in yards. Therefore, to expedite the shipping process, it is crucial to know the exact location of each container at all times. The thesis will also analyze container terminals and their safety elements, as well as the technologies used in modern container terminals. A special chapter will focus on information systems at container terminals, their types, and their activities.
