In this study, evaluation of safety of avoidance width information display and presentation support system, which displays and presents "avoidance width" information necessary to prevent entry of other vessels into collision risk area for the sake of avoidance of a collision, is discussed. The safety of support information was investigated through quantitative evaluation of safety improvement factors of the navigation, based on avoidance width display and presentation information appearing on the ARPA screen built into vessel maneuvering simulator, and avoidance maneuvering experiments performed using vector information as the watch information. As a result of the evaluation, the following findings are obtained: With avoidance width information display system, degree of risk at avoidance maneuvering is reduced to approximately 22% if degree of risk of avoidance maneuvering by ARPA vector display system is normalized to 100% for quantitative indication. In other words, compared with navigation safety at avoidance maneuvering using ARPA vector display system, the same using avoidance width information display system is improved by approximately 78%.
