摘要:

为大范围、高精度地研究船舶交通流特征,引入场方法对船舶交通流进行分析.该过程基于理想的网格布置,以AIS船舶交通流数据为样本值,运用Delaunay剖分进行三角插值,得到船舶交通流流场分布图.与实际交通流情况的对比分析表明,场的形式能够较好地表征船舶交通流分布特征和航行水域安全状态;采用船舶交通流流场分析结果,可以提高船舶航行安全预警和海事安全监管的有效性.

Abstract:

In order to investigate the characteristics of vessel traffic flow extensively and accurately, a field method was introduced to analyze the vessel traffic flow. Based on the ideal grid arrangement, this process used the AIS data of vessel traffic flow as samples and applied Delaunay subdivision for trigonometric interpolation to obtain the distribution diagram of vessel traffic flow field. The comparison with the actual traffic flow shows that the form of field can well characterize the distribution of vessel traffic flow and the safe state of navigation area. Utilizing the analysis results of vessel traffic flow field, the effectiveness of safety prewarning of ship navigation and maritime safety supervision can be improved.
