The invention discloses a channel high-risk point judgment method based on ship conflict analysis, and the method comprises the steps: obtaining channel ship AIS historical data; the method comprises the following steps of: dividing route sections from a channel starting point by continuously taking a sea distance X from the channel starting point as a center, analyzing AIS historical data (time, longitude and latitude, speed and course) of ships in the route sections, and establishing an AIS data storage table and a traffic conflict number data table of the route sections; according to the method, the historical AIS data and the channel related data of the channel to be judged are input, so that the judgment of the high-risk waypoints and the distribution thereof based on the ship conflict analysis can be quickly and accurately carried out.
本发明公开一种基于船舶冲突分析的航道高风险点判断方法,一种基于船舶冲突分析的航道高风险点判断方法,获取航道船舶AIS历史数据;从航道起点开始,连续以距航道起点X海里为中心划分航路段,分析航路段内船舶AIS历史数据(时间、经纬度、速度、航向),建立航路段AIS数据存储表和交通冲突数数据表。本发明提供一种输入待判断航道的历史AIS数据和航道相关数据,就可以快速、准确的进行基于船舶冲突分析的高风险航路点及其分布的判断。
