AI Technical Summary

Technical Problem

Existing technologies fail to effectively consider the characteristics of restricted waterways and the uncertainties caused by environmental and human factors during actual ship navigation risk assessment in port waters, resulting in inaccurate risk assessments.

Method used

By employing a method based on the fusion of AIS and GIS data, the method acquires ship AIS data for preprocessing, grid construction, risk assessment, and visualization. Combined with dynamic feature extraction, trajectory anomaly removal, and adaptive risk diffusion mechanisms, it achieves multi-dimensional modeling and dynamic fusion analysis of ship behavior and the aquatic environment.

Benefits of technology

It improves the accuracy and interpretability of vessel navigation risk assessment in port waters, supports risk-based risk management and intelligent scheduling, and provides efficient and scientific decision support for port safety management.
