日本語
本研究は、AIS履歴とオンラインセンサーを活用した社会認知ナビゲーション枠組み（SCNF）を提案し、自律船舶の衝突回避と航行効率を両立させる。再帰的ハイパーグラフTransformerとLevel-k推論、可読性を考慮したゲーム理論プランナーを統合し、500回のモンテカルロ試行で既存手法を上回る安全性と効率性を示した。ただし燃料消費やCO2排出は直接測定されておらず、低炭素効果は航行レベルの証拠に留まる。
English
This study proposes a Social-Cognitive Navigation Framework (SCNF) using historical AIS trajectories and online sensor data to improve autonomous ship safety and efficiency. Integrating a Recursive Hypergraph Transformer, Level-k reasoning, and a legibility-aware game-theoretic planner, SCNF outperforms baselines in 500 Monte Carlo trials. However, fuel consumption and carbon emissions were not directly measured, so sustainability benefits remain navigation-level evidence.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は海事分野のGX（船舶の電動化・水素燃料等）と自律航行の実用化を推進しており、本論文の効率的な航法設計は運航コスト削減や排出削減に間接的に寄与しうる。ただし国内のSSBJ開示やScope3算定への直接的な示唆は限定的である。
In the global GX context
Global shipping decarbonization is a key focus under IMO's GHG strategy and TCFD/ISSB disclosure for maritime transport. This paper contributes to autonomous navigation efficiency, which can indirectly reduce fuel use and emissions, but it does not provide quantified emission reductions or link to disclosure frameworks.

📄 Abstract（原文）
Introduction The digital transformation of maritime transportation creates new opportunities to improve the safety, efficiency, and sustainability of autonomous shipping. However, existing navigation methods often emphasize collision avoidance and trajectory feasibility while paying less attention to unnecessary maneuvering, traffic disturbance, and associated operational demand. Methods This study proposes a data-driven Social-Cognitive Navigation Framework (SCNF). Historical Automatic Identification System (AIS) trajectories are used to extract representative encounter patterns, while online AIS and onboard-sensor data are treated as partial and asynchronous observations. SCNF integrates a Recursive Hypergraph Transformer, recursive Level-k reasoning, and a legibility-aware game-theoretic planner. Performance is evaluated using safety, efficiency, interaction, and disturbance metrics across 500 Monte Carlo trials. Results SCNF outperforms representative reactive, optimization-based, and learning-based baselines. In the complex crossing scenario, it achieves a 0% collision rate, 15.2 m minimum distance of approach (MDA), 1.08 normalized path length, 4.1° Average Avoidance Magnitude by Others (AAMO), and 4.6/5 Trajectory Legibility Score (TLS). In the heterogeneous overtaking scenario, it maintains a 0% collision rate and 18.5 m MDA. Ablation results confirm complementary contributions from the three core modules. Discussion SCNF improves navigation-level safety, efficiency, and interaction coordination while reducing unnecessary maneuvering-related operational demand. Fuel consumption and carbon emissions were not directly measured; therefore, the sustainability benefits should be interpreted as navigation-level evidence rather than quantified real-ship emission reductions.
