Developing a Ship Collision Risk Index Estimation Model Based on Dempster-Shafer Theory
Applied Ocean Research, 2021Abstract A reliable and accurate evaluation of the risk of a ship collision with other vessels is crucial for the avoidance of maritime accidents. The ship operators use the collision risk index (CRI) to detect the risk of a collision and take the necessary action.

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 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.

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

2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2013
The study of vessel collision risk index and decision-making system of vessel collision avoidance has always been at the center of concern for all sailors and navigators. The article proposes the GA-BP algorithm. That is a combination of the Genetic Algorithm and the Neural Network.

A New Risk Evaluation Index for Rear-End Collisions Considering Drivers’ Risk Perception
2012Rear-end collision is a main type of traffic accidents. In this study, we divided collision risks of car-following cases into three types, potential risk, obvious risk, and driver’s subjective risk perception. We designed different experiments to examine performance and parameters of six collision risk judgment indices which have been proposed (e.g ...

Estimation of Mid-Air Collision Risk in High-Density Airspace Using Hexagonal Spatial Indexing
Journal of Intelligent Aeronautical Systems and Sustainable Flight TechnologiesCivil aviation safety remains a foundational element of the modern air transport system. Each of air transportation services must be delivered in compliance with the minimum required safety levels. Contemporary safety assessment frameworks typically integrate the cumulative impact of hazardous factors on the nominal functioning of the air transport ...
