Multi-stage and multi-topology analysis of ship traffic complexity for probabilistic collision detection

A probabilistic analytics method to identify striking ship of ship-buoy contact at coastal waters

“…3 shows the probability distribution of the minimal passing distance between the ship and buoy according to the probabilistic buoy domain based on AIS traffic data. And the buoy domain is obtained by calculating the probability density function using traffic data based on statistical analysis approaches (Zhong et al, 2019;Lei et al, 2021;Gucma and Marcjan, 2012;Xin et al, 2023;Zhang and Meng, 2019).…”

Maritime traffic clustering to capture high-risk multi-ship encounters in complex waters

“…Maritime safety management has always been regarded as one of the essential concerns due to the intolerable ramifications (e.g., loss of life, economic damage, and/or environmental pollution) when maritime traffic accidents occur. Economic globalization associated with the rapid boom in transportation demand has made maritime traffic more sophisticated, especially in restricted waterways and heavy-traffic ports [1][2][3]. This change brings significant challenges to maritime operational authorities on maritime traffic safety management, particularly when the fast development of emerging autonomous ships is considered, which could potentially increase the occurrence likelihood of ship collisions without an effective solution to be found.…”
