Ship’s Trajectory Planning Based on Improved Multiobjective Algorithm for Collision Avoidance

Journal of Advanced Transportation, 2019
With vigorous development of the maritime trade, many intelligent algorithms have been proposed to avoid collisions due to resulting casualties and increased costs. According to the international regulations for preventing collisions at sea (COLREGs) and

A Study on A Novel Collision Risk Prediction Map for Maritime Traffic Surveillance Based on Ship Domain [PDF]

Recently, a regional model for assessing the risk of multi-ship collision has been developed to reduce the risk of ship collision in territorial sea areas such as trade ports and entry waterways and improve the safety and efficiency of ship traffic.

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, Volume 34, Issue 1, Page 337-371, January 2027.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Vehicle Fires: Significant Fire Hazard in Transportation Infrastructure

Fire and Materials, Volume 50, Issue 8, Page 927-940, December 2026.
ABSTRACT Vehicle flammability poses a critical threat to transportation infrastructure, with recent fires in depots, tunnels, and car parks highlighting systemic vulnerabilities. These incidents often result in the total loss of vehicles and buildings, revealing the inadequacy of current fire safety standards for vehicle materials.

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 ...

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, Volume 1, Issue 4, December 2026.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.
