This thesis will analyze the importance of the TEN-T network for transport connectivity throughout the European Union, which represents a key factor in economic and social progress. The TEN-T network consists of several corridors that connect into a single network. The work focuses on the Mediterranean Corridor and on the impact of the port of Barcelona, as one of the largest and busiest hubs within this corridor of the TEN-T network. Through the analysis of the operations of the Port of Barcelona, it will be seen how the development of the Mediterranean TEN-T Corridor is affected through the implementation of new technologies, the improvement of multimodality, the application of practices to reduce the ecological footprint. Inside the port of Barcelona, the development of the logistics operations itself is persistently developed, and the port of Barcelona serves as an example of logistics development. The progress of the port of Barcelona has a positive impact on the Mediterranean TEN-T corridor, but also on the economy of the autonomous province of Catalonia and the state of Spain. The thesis contributes to a better perception of how the mutual correlation of the application of new technologies with the key factor of sustainability has a great positive impact on the infrastructural transport projects of the European Union.
