Safe and efficient vessel traffic flow is the overall aim of maritime transportation. Each of the different components of the transportation system contributes to this aim. The current situation is characterized by substantial changes in the maritime world. They are caused by he introduction of new technologies and the implementation of e-Navigation concept. This concept bases on sustainable digitalization and ambitions and may once allow for unmanned and autonomous shipping. Basing on participant observation, this paper analyzes the present situation from the perspective of shore-based vessel traffic management elements and suggests an approach to address rising challenges by research.
