项目摘要

The object of this research is a visual check on the lookout in the maritime traffic system. The summary of the obtained main conclusion is summarized as follows. The visual check condition of the horizon clarified that the luminance difference between sky luminance and the sea surface luminance was greater than that of the difference luminance threshold to sky luminance from the relation between a physical characteristic of the outdoors visual environment and the difference luminance threshold. The author showed that the horizontal plane illuminance of the navigation bridge was able to standardize solar altitude as a parameter.The author projected based on the investigation of the case with 1000 collision marine casualties shown in the judgment report the collision marine casualty ratio and showed a lot of environmental conditions etc. In addition, the visual check on the lookout was evaluated, the author proposed the lookout points, and the importance to improve the visual check on the lookout was confirmed. It is that the target does not necessarily exist that the target is not seen. It means a psychological factor and a physiological factor, etc. should be considered by a proper lookout.The author proposed to introduce the concept of the visual check on the ship "Visibility level (VL)". The author proposed the lookout points in the navigation bridge as follows according to the distance.(1) 6 nautical mile beyond : "Visual check difficulty area", (2) 3-6 nautical miles : "First recognition area", (3) within three nautical miles : "Observation area"As a result, the field factor was guessed regardless of unlike the visual environment at sea shown by solar altitude even though about three at sea.The problem in the future is to catch the entire maritime traffic system by the viewpoint of disaster prevention, and to examine each element for Machine Factors and Management Factors.

这项研究的目的是对海上交通系统中的监视的视觉检查。所获得的主要结论的摘要总结如下。地平线的视觉检查条件澄清说，天空亮度与海面亮度之间的亮度差异大于差异亮度阈值到天空亮度的亮度阈值来自室外视觉环境的物理特征与差异亮度阈值之间的关系。作者表明，导航桥的水平平面照明能够将太阳高度标准化为参数。作者根据对案件的调查进行了投影，其中1000次碰撞海上伤亡中显示了判决报告中的1000次碰撞海洋伤亡，碰撞海上伤亡比率是碰撞海洋的伤亡比率，并显示了许多环境条件。此外，还在查看了探测型号的观察点。确认的。目的是不一定存在目标。这意味着应通过适当的监视量考虑心理因素和生理因素等。作者提议在“可见性水平（VL）”上介绍视觉检查的概念。作者提出了导航桥上的监视点，如下所示。（1）6海里超出：“视觉检查难度区域”，（2）3-6海里：“第一个识别区域：（3）在三个航海里程内：“观察区域：“观察区域”，因此，无论是在海上奔跑的环境而言，田地因素都与sea nytive nythe Iss Sea所示，即使是在海上的情况下，无论是在海上的情况下，均不在海上。海上交通系统通过预防灾难的观点，并检查每个元素的机器因素和管理因素。
