Since aids to navigation play an important role in ensuring that ships navigation safely on fairway, many countries periodically review the suitability of aids to navigation placement. In this study, algorithms using distance ratio concept and aids to navigation’s placement standard were implemented to verify the suitability of new aids to navigation placement verification using machine learning, and a system applicable to fairway was developed. By presenting a method for verifying the suitability of aids to navigation placement, a quantitative evaluation tool for aids to navigation placement was prepared, and a user-friendly evaluation standard was prepared through the design of a aids to navigation placement verification system using big data of navigating vessel through the fairway.
