A Study on Multi-ship Avoidance System for Unmanned Surface Vehicles Using the Quaternion Ship Domain and Collision Risk Index

한국해양공학회지
Collision avoidance is essential for the safe navigation of unmanned surface vehicles (USVs). This paper proposes a multi-ship collision avoidance algorithm that integrates the quaternion ship domain (QSD) and collision risk index (CRI) to assess ...

Collision Risk Inference System for Maritime Autonomous Surface Ships Using COLREGs Rules Compliant Collision Avoidance

IEEE Access, 2021
Maritime autonomous surface ships (MASS) need to be sufficiently safe to gain commercial acceptance. Collision avoidance strategies in such MASS should comply with the International Regulations for Preventing Collision at the Sea (COLREGs).

Train Collision Risk Index for Anti-collision Assessment and Early Warning Method Based on Neural Network

Journal of Physics: Conference Series, 2021
Abstract Collision Risk Index is used as the criteria for measuring collision occurrence. This paper introduces Collision Risk Index into the field of rail transit after analyzing the rationality and feasibility to analyze the collision problems in the train operation process.

Inference Model of Collision Risk Index based on Artificial Neural Network using Ship Near-Collision Data

Journal of Physics: Conference Series, 2019
Abstract The judgement of Collision Risk Index (CRI) is important for safe navigation. The autonomous ship need to analyze and decide taking an action for collision avoidance. Recently, it has been possible of navigator to obtain navigation information in real time.

Real-Time Web-Based Ship Collision Risk Detection Using AIS Data and Collision Risk Index (CRI)

sinkron
The high density of maritime traffic in Indonesian waters, particularly in the Lombok Strait and Nusa Penida region, increases the risk of ship collisions, especially among vessels lacking adequate navigation systems. This study presents the development of a web-based system for real-time ship monitoring and collision risk assessment using Automatic ...

Increase in rear-end collision risk by acute stress-induced fatigue in on-road truck driving

PLoS ONE, 2021
Increasing road crashes related to occupational drivers’ deteriorating health has become a social problem. To prevent road crashes, warnings and predictions of increased crash risk based on drivers’ conditions are important.

Relationship between truck driver fatigue and rear-end collision risk

PLoS ONE, 2020
The fatigue of truck, bus, and taxi drivers has been a causal trigger for road accidents. However, the relationship between collision risk and the extent of objective fatigue has yet to be confirmed.
