In the early period of a research to assess marine traffic environment, statistics were usually used as an index. However, statistics are lacking in quality assessment, so the trend of the research to assess marine traffic environment has been changing to a standpoint of a navigator. When the marine traffic was treated as a man-machine system, a ship-handling simulator becomes a useful tool in order to assess difficulty of the encounter situation based on navigator's sense. Research like this is very important to keep marine traffic safety because of heavy traffic in Japan. However, there is a limit to evaluate a lot of encounter situations by experiments using a ship-handling simulator because of limit of time, cost and so on. So, the new experimental method using a bird's-eye picture and using the analytic hierarchy process (AHP) was carried out to assess difficulty of fourteen typical encounter situations. This experimental method has several good points. At the first, no large-scale equipment and no long experiment time are needed. The second, differences between individuals in sense are solved by mutual consent and a consistent result is obtained by AHP. Five pilots on actual service engaged in this new experiment. As the results, the degree of difficulty of typical encounter situations and effectiveness of this experimental method were confirmed.
