Towards Marine Collision Avoidance Based on Automatic Route Exchange

In order to provide reliable collision avoidance in narrow waterways and the open sea we propose a new approach for traffic management and collision avoidance which incorporates uncooperative vessels in the planning process. Trajectories for each vessel will be planned, distributed and optimised between all actively engaged vessels, which follow the suggested procedure. The behaviour of vessels which cannot contribute towards a common solution will be assumed using probabilistic models, based on historic AIS data. In a bargaining process active vessels will negotiate their trajectories in order to find an optimal trajectory for each vessel within given constraints. Implemented in, for example, an Electronic Chart Display and Information System the resulting system can assist sea-faring personnel in their judgement of an encounter situation and suggest a trajectory automatically agreed upon by the system with all other vessels in the area.
