Abstract — 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.
