Towards a decision support system for maritime navigation on heavily trafficked basins

Therefore, this paper shows the concept of the Multi-ARPA (MARPA) system along with case studies. The system is intended to deliver to a navigator on board ship information on safe headings while encountering other ships. The safe headings are determined based on the level of hazard that other ships create or will create once the heading of the own ship is altered. The system may evaluate and visualize safe heading adopting multi-level or binary classification. The presented system operates on the basis of an algorithm designating direct hazards for the own ship for the set of manoeuvres in an encounter situation for numerous ships.
