Collision Risk Model for Encounter Situation Assessment Based on Empirical Observations

The safe navigation of vessels at sea requires a detailed awareness of possible hazard situations. This work, presents a method to analyze and assess the collision risk considering conditions like bad visibility and rough seas in addition to the risk measurement for risk assessment and near miss detection. For an objective assessment of the current subjective perception of encounter situations, the empirical evaluation of historical observation data of the German coast forms the basis. A process for the extraction and analysis of vessel encounter situations from traffic, weather and chart data forms the basis. Finally, the method will be evaluated in terms of well-definedness, validity, objectiveness and applicability.
