We present a method for communicating
navigation information that will assist operators to prevent
maritime disaster. Although this topic has been extensively
researched, the navigational situation of vessels has received
little attention. However, such a navigational situation is
essential for understanding water bodies and ensuring
maritime safety. To provide effective navigation information,
this study first analyzes the actual situation of vessel traffic
using Automatic Identification System (AIS) data. Operators
can be based on the analysis to understand the trend of
navigation ships in water bodies as an important reference.
From the results of the analysis, we constructed a representable
navigational information system. Different information was
unified on a Geographical Information System (GIS) in twoand
three-dimensional formats. The system was demonstrated
in a navigation simulation of a real voyage ship in Osaka Bay,
Japan. The integrated information can be comprehensively and
realistically interpreted by operators. Therefore, the system is
expected to effectively avoid maritime disaster.
^^^^ This situation is especially
dangerous for ship operators with immature navigation
experience because the danger is compounded by stress.^^^^
Therefore, the provision of navigational information has
become timely and important.^^^^^ Over the past years, several
studies have focused on the presentation of navigational
information. However, little attention has been devoted to the
actual navigational situation of vessels, which is essential for
understanding water bodies and ensuring maritime safety.
