Abstract An index for real-time collision risk assessment is the basis for the safe navigation of ships. To consider dimension related factors more accurately and objectively in the collision risk index, and to enhance the readability of the index in collision avoidance decision-making, we propose a novel index by combining the dimension data from ...

A Study on the Collision Risk Perception Index to OOW's According to Vessel Encountering Situations
Journal of the Korean Society of Marine Environment and Safety, 2016The purpose of this study is for Human error prevention to acquire Collision Risk Perception Index (CRPI) sensed by the Officer Of the Watch (OOW) when the approaching distances are reduced in six types of ship encountering situations (Head on, , , , Overtaking, Overtaken) between own ship and a target ship and then to predict CRPI fitting coefficients

A Dynamic Conflict Probe and Index of Collision Risk
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1996We present a mathematical index of colllision risk and propose it as a candidate conflict probe for use in free flight. The index can be used to aid and measure ATC and pilot performance during simulated or real flight. The instantaneous value of the index is a relative (ordinal) measure of global situational risk.

Collision Risk Hotspot Identification Based on AIS Data and DBSCAN Algorithm
International Conference on Transportation Information and Safety, 2023The objective of the present study is to identify ship near-miss areas and identify the hotspot waters with higher collision risks. The Automatic Identification System (AIS) data from the waters near Zhoushan Island is used in the study.
