Fuzzy Collision Threat Parameters Area (FCTPA) - A New Display Proposal
1 Gdańsk University of Technology, Gdańsk, Poland
ABSTRACT: The paper introduces a visualization method that enables the navigator to estimate an encounter situation and choose collision avoidance manoeuvre if necessary. It is based on the CTPA method and offers new features: fuzzy sectors of forbidden speed and course values and the possibility to use any given ship domain. The method is fast enough to be applied in the real-time decision-support system.
