基于熵权法的水上交通安全因素

A Study on Influencing Factors of Maritime Traffic Safety with Entropy Weight Method

由于影响水上交通安全因素较多,分析不同影响因素的重要性对研究水上交通安全有重要意义。以问卷方式分别调查海事管理人员、船员和引航员等3类人员对影响水上交通安全因素的看法。基于调查问卷结果,采用熵权法对影响因素进行重要性排序,并对3类人员的排序进行两两相关性检验。结果表明:3类人员对影响深圳西部水域水上交通安全的因素总体看法一致,最重要的影响因素是能见度和航道条件;两两相关性分析显示海事管理人员与船员和船员与引航员之间为中度线性相关,而海事管理人员与引航员之间为低度线性相关,这表明3类人员对风险因素的排名总体一致,此水域现阶段交通资源存在短缺和亟待改进的问题。该研究结果对制定此水域交通政策和提高水上交通管理服务水平具有重要的意义。

The knowledge on maritime traffic safety is collected from 3 groups of practical workers(maritime regulators,mariners and pilots)through questionnaire and the factors affecting the safety are identified.Influencing factors of safety are sorted in the order of significance by means of entropy weight method.The 3 groups of people who play different roles in traffic process generally agree that the visibility and waterway situation are two most significant factors in Western Shenzhen waters.However,further study shows the discrepancy in their opinions.The opinions of regulator group and mariner group are mediumly correlated and so are those of mariner group and pilot group,but opinions of regulator group and pilot group only have low correlation.
