Abstract

Enhancing Situation Awareness (SA) is crucial for maritime traffic safety. Various indicators have been developed to assess risks in encounter situations and support the SA of Vessel Traffic Service Operators (VTSOs) and Officers on Watch (OOW), including collision risk and traffic complexity. Despite the widespread use of these navigational aids, ship collision incidents have not been effectively reduced. This paper abstracts ship encounter situations as linear dynamic systems to enhance the understanding of traffic situations. A traffic advisory framework based on the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs) is proposed by integrating complexity metrics with risk indicators. The proposed method is validated through simulations of head-on, overtaking, and crossing scenarios, demonstrating its ability to accurately assess encounter complexity and issue advisories for free navigation, complexity, and resolution. Finally, we discuss the practical application of the proposed method through real-world experiments conducted in the waters of Qiongzhou Strait. The results indicate that the proposed method effectively quantifies the complexity of ship encounter situations and identifies high-collision-risk vessels from a microscopic perspective while providing insights into maritime traffic surveillance from a macro perspective.

基于线性动态系统的船舶相遇情况交通咨询
加强态势感知(SA)对海上交通安全至关重要。目前已开发出各种指标来评估遭遇情况下的风险,并为船舶交通服务操作员(VTSO)和值班人员(OOW)的态势感知(SA)提供支持,包括碰撞风险和交通复杂性。尽管这些导航辅助工具得到了广泛使用,但船舶碰撞事故并未得到有效减少。本文将船舶遭遇情况抽象为线性动态系统,以加深对交通情况的理解。通过将复杂性指标与风险指标相结合,提出了基于《国际海上避碰规则公约》(COLREGs)的交通咨询框架。通过模拟迎面、超车和交叉场景,对所提出的方法进行了验证,证明了该方法能够准确评估遭遇复杂性,并针对自由航行、复杂性和解决方法发布建议。最后,我们通过在琼州海峡水域进行的实际实验讨论了所提方法的实际应用。结果表明,所提出的方法能有效量化船舶遭遇情况的复杂性,并从微观角度识别高碰撞风险船舶,同时从宏观角度为海上交通监控提供见解。

期刊介绍: Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
