STUDY ON MARINE TRAFFIC ACCIDENTS--DEGREE OF DAMAGE AND ESTIMATION OF LOSSES RESULTING FROM MARINE TRAFFIC ACCIDENTS

The damages to 3,238 vessels involved in collisions and to 1,841 stranded vessels are surveyed. Analytical representation of the relative frequency distribution function, f(x,y), is obtained as the result of the survey, where x is the degree of damage and y is the gross tonnage ratio of vessels in collision. Approximation with the function, f(x,y), yields the average value of the damage rate in a simple form, 0.015y 0.6. This allows estimation of the aggregate sum of economical loss due to collisions in a certain water area from traffic quantities and the probability of collision. Another survey is made on losses due to accidents in Tokyo Bay together with three empirical estimation methods for the same quantities. These results are about two or three times that obtained from calculation with the average damage rate. This discrepancy, however, may perhaps be accepted as a rough preliminary estimate. The above study makes possible a cost-benefit study of the establishment of a traffic management system for a water area in which a traffic survey is made.
