Onboard Measurements of Navigator’s Situation Awareness in Congested Sea Area

Sailing status recognition to enhance safety awareness and path routing for a commuter ferry

“…For example, some scholars build knowledgebased expert systems to support on-board decision (Perera et al 2012;Calabrese et al 2012); some use classical and/or novel control theories and tools to improve the manoeuvrability under particular conditions (Pietrzykowski et al 2010;Nielsen and Jensen 2011); some introduce advanced algorithms to optimise the path planning and navigation (Lazarowska 2012;Simsir et al 2014;Vettor and Soares 2015;Pietrzykowski et al 2017); and some use data from automatic identification system (AIS) to support trajectory reconstruction and path following navigation (Zhang et al 2018;Xu et al 2019). From another view, such a safety awareness system is within the issue of situation awareness which has attracted researchers to focus on for aiding on-board operation (Chauvin et al 2008;Nilsson et al 2008;Fossdal 2018;Li et al 2019;Nisizaki 2019). However, most research items stay in a conceptual stage without mathematical calculation and applicable data utilisation framework.…”
