### Traffic Management Functions in Relation to the Implementation of Regulation (EU)
After summing up the impact of the VTS systems within individual categories, it is possible to distinguish eight tasks [14] on which the VTS systems have the greatest impact:  
* The promotion of economically efficient, high-quality transport contributing to further economic growth and competitiveness;
* Efficient use of new and existing infrastructure;
* Cost-efficient application of innovative technological and operational concepts;
* Contribution to the objectives of low greenhouse gas emissions, low-carbon and clean transport, fuel security, reduction of external costs and environmental protection;
* Promotion of low-carbon transport with the aim of achieving by 2050 a significant reduction in CO\({}_{2}\) emissions, which is in line with the relevant EU CO\({}_{2}\) reduction targets;
* Ensuring safe, secure and high-quality standards for both passenger and freight'transport;
* Supporting mobility, even in the event of natural or man-made disasters, and ensuring accessibility to emergency and rescue services;* The establishment of infrastructure requirements, in particular, in the field of interoperability, safety and security, which will ensure quality, efficiency and sustainability of transport services. Despite the fact that the area managed by VTS Lawica Stupska is not located within TEN-T transport corridors network, it was taken into account because it serves ships calling at ports that are the elements of mentioned network. Moreover, the area managed by VTS Lawica Stupska covers routes essential for short sea shipping. In the authors' opinion, this system also impacts the selected TEN-T tasks. \begin{table}
