Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and technical solutions.

[0023] The required data is extracted from the AIS ship automatic identification system, and the data comes from all the ships entering and leaving the port in 2018.

[0024] A method for analyzing ship navigation characteristics and preferences based on AIS data, the steps are as follows:

[0025] Such as figure 1 As shown, the fixed-routing system meets the two-way traffic of ships, and the ships enter the east entrance and sail westward respectively, and enter the west entrance and sail eastward. object.

[0026] Step 1: Ships are prohibited from navigating in the route separation zone of the route system. At the east entrance of the route system, the length of 200m and the width of 0.5 times the width of the channel are defined as the ship AIS data statistical area at the entrance of the route on the east side of ...

Abstract

The invention discloses a ship navigation feature and preference analysis method based on AIS data and belongs to the field of ship traffic. The ship navigation characteristic and preference analysismethod based on the AIS data, the static information and the dynamic information contained in the ship AIS data are combined, in the navigation operation process of the ship in the navigation channel,the ship speed characteristics of different types of ships in different time periods and the navigation preferences of different types of ships with different ship lengths are explored, the parameters required by the navigation channel and anchorage ground trafficability simulation dynamic simulation research are determined, the pertinence of maritime affair management in ship navigation is enhanced, and management efficiency is improved.

Description

technical field [0001] The invention belongs to the field of ship traffic, and relates to a ship navigation characteristic and preference analysis method based on AIS data. Background technique [0002] The ship's automatic identification system (Automatic Identification System, AIS) can send the ship's AIS data to the shore base station or satellite every few seconds. The AIS data includes three types of information, namely static information, dynamic information and navigation-related information. Static information includes ship name, ship type, ship size, cargo type, etc.; dynamic information includes time, position, ship speed and ship heading, etc.; navigation-related information includes draft, destination, etc. Navigation-related information is manually updated by personnel on board, and the data reliability is not high. Generally, navigation-related information is not considered in AIS data analysis. [0003] The dynamic information and static information of ship A...
