【摘要】：船舶分道通航制是最常见,应用最广泛的船舶定线措施之一。迄今为止,经国际海事组织(InternationalMaritime Organization,IMO)采纳的分道通航制已经达到160多个。作为一种先进的海事管理理念,船舶分道通航制对优化船舶交通流、保证船舶航行安全有着重要意义。因此,分道通航制被广泛应用于船舶交通流汇聚和事故高发水域。本文对IMO采纳的分道通航制进行了详细的统计分析,统计的具体内容包括设立水域、所属国家、离岸距离、航道长度、航道宽度、分隔带宽度、分隔带形状、转向角度以及分道通航制和其他定线制措施的组合使用情况。针对设立水域特点的不同,本文将分道通航制设立的水域分为岛礁区水域、岬角水域、峡水道水域、沿海水域和开敞水域,并对不同水域的分道通航制设计要素进行了详细的对比和分析,得到了不同水域分道通航制设计的规律。在此基础上,采用聚类分析方法对分道通航制进行了重新分类,克服了按水域分类的局限性,得到了更加科学的分类,并以东拉马和蓝塘海峡船舶分道通航制等为例,演示了如何采用Fisher判别法确定新的分道通航制所属类别,以及如何使用相关系数法和夹角余弦法计算其与所属分道通航制类别的相似度,从而为分道通航制设立提供合理的建议。最后本文以成山角分道通航制作为实例分析了如何利用本文的研究内容节约分道通航制的设计时间并提高设计的准确性。基于聚类分析方法和Fisher判别法的分道通航制设立规律的研究对分道通航制的建立和分道通航制的修订都具有一定的参考和借鉴意义。
[Abstract]:Ship routing system is one of the most common and widely used ship routing measures. To date, the International Maritime Organization (IMO) has adopted more than 160 traffic separation schemes. As an advanced concept of maritime management, ship routing system is of great significance to optimize ship traffic flow and ensure ship navigation safety. Therefore, traffic separation system is widely used in marine traffic flow converging and accident-prone waters. This paper makes a detailed statistical analysis of the traffic separation system adopted by IMO. The specific contents of the statistics include the establishment of waters, the country to which it belongs, the distance from shore, the length of the channel, the width of the channel, the shape of the separation zone. Steering angle and combined use of traffic separation system and other routing measures. In view of the differences in the characteristics of the established waters, this paper divides the waters set up under the system of traffic separation and navigation into the islands and reefs, headland waters, isthmic waterways, coastal waters and open waters. The detailed comparison and analysis of the design elements of the diverging navigation system in different water areas are carried out, and the rules of the design of the separate navigation system in different water areas are obtained. On this basis, the method of clustering analysis is used to reclassify the traffic separation system, which overcomes the limitation of the classification according to the water area, and obtains a more scientific classification. As examples, the ship separation system in the East Lamar and the Lantang Strait is taken as an example. This paper demonstrates how to use Fisher discriminant method to determine the classification of the new traffic division system, and how to use the correlation coefficient method and the angle cosine method to calculate the similarity between the classification of the system, Therefore, reasonable suggestions are provided for the establishment of traffic separation system. Finally, taking Chengshan corner as an example, this paper analyzes how to save the design time and improve the accuracy of the design by using the research content of this paper. The study on the rules of setting up the separated navigation system based on the clustering analysis method and Fisher discriminant method has certain reference and reference significance for the establishment of the separated navigation system and the revision of the separated navigation system.
