Abstract
In order to accurately and objectively reveal the relationship between ship domain, ship type and ship size near traffic lanes of open water, a method to determine ship domain boundary based on ship automatic identification system (AIS) data was proposed firstly, i.e, a large amount of AIS data was used to calculate the relative position relationship between ships, and the relative position relationship between ships in different time and space was stacked together. In this way, the distribution of other ships around the center ship is reflected. Secondly, an integrated platform of ship domain analysis was designed, and by combining with the distribution of surrounding ships, the least square method was used to fit the domain boundary, and the ship domain in the study area was obtained. Finally, taking certain traffic lane water as example, the ship domains of the main ship types were studied. Results show that the ship domain in traffic lane of open water is near elliptical, which is similar to the Fujii ship domain model. The ship domain is related to ship size and ship type, and increases with the increase of ship size. In the same size, cargo ship domain is smaller than oil tanker, and the long axis of domain is more significant than the short axis as the ship length increases.
