Abstract

Overtaking in restricted waterways is a common navigation scenario with a high risk of collision due to ship-ship interaction and unexpected events. This paper proposes an analytical method for assessing overtaking risk in busy waterways by considering both longitudinal and transverse safe distances. The approach involves establishing a three-layer overtaking risk framework that identifies the influencing factors through scenario analysis of ship overtaking, ship-ship interaction, and ship-following. The safe criteria for fuzzification in both longitudinal and transverse directions are defined, and the overtaking risk is integrated using fuzzy logic. The proposed approach is applied to 100 historical data in the Yangtze River, and the results of high and very high overtaking scenarios show that the model provides a practical and reasonable assessment of ship overtaking risk. The proposed model can be used as decision support for ship navigation in busy waterways.
考虑船-船相互作用的受限水域船舶超车风险建模
限制航道超车是一种常见的航行场景,由于船-船相互作用和突发事件,超车的碰撞风险很高。本文提出了一种同时考虑纵向和横向安全距离的繁忙航道超车风险评估分析方法。该方法通过对船舶超车、船-船相互作用和船舶跟随的情景分析,建立三层超车风险框架,识别影响因素。定义了纵向和横向模糊化的安全标准,并用模糊逻辑对超车风险进行了综合。将该方法应用于长江100条历史数据,高超车和极高超车情景的结果表明,该模型对船舶超车风险进行了实用、合理的评估。该模型可作为繁忙航道船舶航行的决策支持。
