Aiming at improved navigation safety, this paper examines the method for evaluating the safety of collision prevention support system. Watch operation "to spot dangerous vessel and to find relief area" by the person at the steering wheel was simulated on CRT to investigate how the reliability and burden of visual information processing operation were affected by the manner in which the visual information was displayed. ARPA images were simulated on CRT and a series of wacth operations were repeated using personal computer to measure the reliability of visual information processing and the burden of the operation. Following results were obtained. ・Time duration for deciphering the visual information varies depending on how the information is displayed. ・Improved method of displaying the visual information requires less time in deciphering and reduces the burden on the personnel in charge of the operation. ・Reliability of the improved mode of information processing is increased. We were able to obtain valuable suggestions regarding the improvement of the conventional ARPA display.
