Abstract
There are a lot of maritime accidents caused by human factors. The experiment using bridge simulator is effective for analysis of the human factor. However, the analytical approach for the navigational behavior by the experiment with bridge simulator has not been established yet. The purpose of this paper is to propose an analytical approach by the experiment using bridge simulator that finds out the important factor to avoid accidents. As a result of the experiments and the analysis, it is clearly important that the officers judged the necessary of the constant lookout for dangerous targets. The analytical approach is effective to find the important factor to avoid accident.
