Maritime traffic is an environment where
various stakeholders, such as bridge teams, marine pilots, captains, vessel
traffic services operators (VTSOs), fishermen, and local traffic, collaborate
and regulate operations. The increasing number of monitored ships in coastal
areas, as well as the diversity and volume of operations, have contributed to
an increased workload for maritime traffic stakeholders. This study aims to
examine the treatment of workload in maritime literature and present a
comprehensive framework for understanding workload trends over time through
relational analysis. The research started with scanning articles retrieved from
the Web of Science and Scopus databases. As a result of the scanning process,
abstracts of 372 documents related to the topic were obtained and these files
were merged. In the analysis of the documents using the VOSviewer program, it
was observed that Murai K. (41), Hayashi Y. (30), and Okazaki T. (15) are the
most prolific authors. Murai K. is the author with the highest number of
citations in this field, with 200 citations. Japan ranks first with 56
publications, followed by the United States (39), China (35), and the United
Kingdom (27). Subsequently, the documents were analyzed using methods such as
word frequencies, code clustering maps, and relational analyses based on years
using the MAXQDA Analytics Pro 2022 software. The analysis revealed that the
concept of workload in the maritime domain has a 50-year history, with the most
commonly occurring terms after keywords being mental, human, factor, safety,
performance, navigation, fatigue, operation, data, and simulator. Furthermore,
mental workload emerged as the predominant aspect of measurement, with
physiological indicators such as salivary amylase, nasal temperature, and heart
rate commonly employed. While there has been an increase in research in recent
years, the study highlights a limited focus on workload specifically within the
field of VTSOs, with the majority of studies primarily examining workload among
ship crew members.
