視程の変化による操船者への影響

抄録

The visual information which the navigator accepts varies by the visibility. If the comparison of the statistical value to assess the situation, increase or decrease of its information value by the variation of statistical value is shown quantatively. But it is quite difficult to analysis all of them using the whole factors. So in this paper, the authors marked to the difference of the timing for collision avoidance maneuvers, the bridge simulator experiments were carried out using the Fuzzy inference. As the results, it became clear that Fuzzy dangerous (J-value) at the timing of the collision avoidance maneuvers is almost stable. And it is found that it will be later to execute collision avoidance maneuver when the visibility will be worse.
