Maritime Anomaly Detection for Vessel Traffic Services: A Survey

A Vessel Traffic Service (VTS) plays a central role in maritime traffic safety. Regulations are given by the International Maritime Organization (IMO) and Guidelines Association of Marine Aids to Navigation Lighthouse Authorities (IALA). Accordingly, VTS facilities utilize communication sensor technologies such as an Automatic Identification System (AIS), radar, radio others. Furthermore, operators motivated apply Decision Support Tools (DST), since these can reduce workloads increase promising type DST is anomaly detection. This survey presents overview state-of-the-art approaches detection for surveillance traffic. The characterized context and, thus, most notably, sorted according utilized technologies, addressed types underlying techniques. On this basis, current trends well open research questions deduced.
