COLREGs-Compliant Distributed Stochastic Search Algorithm for Multi-Ship Collision Avoidance

Journal of Marine Science and Engineering
The increasing complexity of maritime traffic imposes growing demands on the safety and rationality of ship-collision-avoidance decisions. While most existing research focuses on simple encounter scenarios, autonomous collision-avoidance strategies that ...

The Effect of High Ship Speed Ratio on Collision Avoidance Behavior of COLREGS [PDF]

TransNav, 2019
The speed ratio is an important factor that must be considered when two vessels will course change to avoid collision. In the process of the research on Personifying Intelligent Decision-making for Vessel Collision Avoidance (short for PIDVCA), it is ...

The Colregs and the Princess Alice [PDF]

TransNav, 2007
There is currently considerable interest in the international regulations for preventing collisions at sea (the Colregs). Suggestions for changes are made, but their validity is difficult to assess because, apart from some very limited simulator ...

EDA: New System for Improving Navigation Standards (Totem Plus) [PDF]

TransNav, 2017
EDA is a tool for auditing vessel?s performance that helps installing strict safety navigation standards on ships. The practice of investigating every near-miss event is common in aviation, but unheard of in the maritime industry. At the same time, major

DSSA+: Distributed Collision Avoidance Algorithm in an Environment where Both Course and Speed Changes are Allowed [PDF]

TransNav, 2019
Distributed Stochastic Search Algorithm (DSSA) is one of state-of-the-art distributed algorithms for the ship collision avoidance problem. In DSSA, whenever a ship encounters with any number of other ships (neighboring ships), she will select her course ...
