Legal applications are complicate so that laws and ordinances have priority structure, special conceptional structure and unique logical structure, and legal knowledge has the classification such as laws, regulations, precedents, legal theories, legal common sense and so on. Especially maritime traffic laws and regulations were legistlated as legal norm which stipulated custom and empirical rules, and had character with judicial norm other than maneuvering norm (behavior norm). This research has interdisciplinary character as foundations in traditional jurisprudence, symbolic logic, legal logic and information science, and forms one province of jurimetrics aiming at scientific approach of law by empirical method. The idea of jurimetrics can be applied to systematization of laws and ordinances. In this research, I clarify legal knowledge structure and discuss a method theory of systematization for the maritime traffic laws and regulations through an approach of jurimetrics for legal thought.
