EARLY DETECTION OF VESSEL COLLISION SITUATIONS IN A VESSEL TRAFFIC SERVICES AREA
Transport, 2019 This study presents enhanced collision detection model in a Vessel Traffic Services (VTS) area. The proposed detection method of collision situations is based on the assumption that VTS station is provided with passage plans of all the vessels in a monitored area. By using an early detection model for prediction of possible collision situations,

Semantics analysis model based on deep learning for vessel traffic service application
IET Intelligent Transport Systems, 2023 Vessel Traffic Service (VTS) significantly improves the navigation efficiency of ports. This paper proposes a model called Joint Extraction of Triples from the VHF Speech (JER‐VHF) to ensure the efficiency of the VTS.

Impacts of AIS Temporal Asynchrony on False-Negative Risk in CPA-Based Near-Miss Detection
IEEE AccessAutomatic Identification System (AIS) data are widely used for maritime traffic monitoring and near-miss detection. Most detection approaches based on the closest point of approach (CPA) implicitly assume that AIS reports from different vessels are ...
