The extended system of Ship Auto-navigation Fuzzy Expert System (SAFES) is proposed, which is applicable even for narrow and congested waterways. SAFES is an expert system using fuzzy reasoning and control as well as regulations, captain's experiences and knowledge as knowledge bases. It also includes the visual information understanding for waterway boundary detection. The system is applied for safety assessment of a waterway design, combining with marine traffic simulation system. In this method, the assessment can be done qualitatively, quantatively and statistically. The alternatives of waterway design can be evaluated, considering the effect of traffic.
