A maritime route is used by sea transportation vessels to access the trading ports, and route design standards for the safety of maritime traffic have been established in various countries and organizations. However, no quantitative safety verification method related to route design currently exists. In this study, a novel maritime route was created and compared with the original route in Incheon, the Republic of Korea, based on the relevant automatic identification system (AIS) data. The attendant traffic density was revealed via kernel density estimation analysis of the AIS data, with the results used to create the boundary of the novel route through an image processing technique. The boundary and the centerline of the maritime route were determined using a line smoothing technique. For safety verification, the centerline of the original route and that of the novel maritime route were compared in terms of sinuosity, intersection angle, and route change envelope (RCE). The sinuosity analysis demonstrated that the route was stable in terms of the outer harbor limit, while the intersection angle analysis demonstrated that the novel maritime route intersection angle was stable. The RCE was used to objectively compare the absolute values of the distance change in the centerline.

核密度估计分析与自动识别系统数据对新型海路提取的验证

海上运输船使用海上路线进入贸易港口，并且在各个国家和组织中已经建立了海上交通安全的路线设计标准。但是，目前不存在与路径设计有关的定量安全验证方法。在这项研究中，根据相关的自动识别系统（AIS）数据，创建了一条新颖的海上航线，并将其与大韩民国仁川的原始航线进行了比较。通过对AIS数据的核密度估计分析来揭示伴随的交通密度，其结果用于通过图像处理技术创建新路线的边界。使用线路平滑技术确定海上航线的边界和中心线。为了安全验证，比较了原始航线和新型海上航线的中心线的弯曲度，交叉角和航线变更包络线（RCE）。弯曲度分析表明，该航线在外港范围内是稳定的，而交叉角分析表明，该新型海上航线交叉角是稳定的。RCE用于客观比较中心线距离变化的绝对值。
