Modeling perceived collision risk in vessel encounter situations

Modeling of ship trajectory in collision situations by an evolutionary algorithm

|For a given circumstance (i.e., a collision situation at sea) a decision support system for navigation should help the operator to choose a proper maneuver, teach them good habits, and enhance their general intuition on how to behave in similar situations in the future. By taking into account certain boundaries of the maneuvering region along with information on navigation obstacles and other ...

Adaptive Modeling of a Ship Trajectory in Collision Situations at Sea

For given circumstances (i.e., a collision situation at sea), a decision support system should help the operator to choose a proper maneuver, teach him/her good habits, and enhance his/her general intuition on how to behave in similar situations in the future. By taking into account certain boundaries of the maneuvering region, along with information on navigation obstacles and other moving shi...

Distributed Stochastic Search Algorithm for Multi-ship Encounter Situations

Ship collision avoidance involves helping ships find routes that will best enable them to avoid a collision.When more than two ships encounter each other, the procedure becomes more complex since a slight change in course by one ship might affect the future decisions of the other ships. Two distributed algorithms have been developed in response to this problem: Distributed Local Search Algorith...

Vessel speed restrictions reduce risk of collision-related mortality for North Atlantic right whales

Collisions with vessels are a serious threat to a number of endangered large whale species, the North Atlantic right whale (Eubalaena glacialis) in particular. In late 2008, the U.S. National Oceanic and Atmospheric Administration issued mandatory time-area vessel speed restrictions along the U.S. eastern seaboard in an effort to mediate collision-related mortality of right whales. All vessels ...
