In focusing on the manner in which drivers recognize extraordinary events occurring in front of them, visual searching is crucial. l'he purpose of this study is to investigate efiective visual searching in recognizing extraordinary events based on the eye movements of drivers. One hundred twenty one drivers of a railway company participated in our study. An experiment was conducted using a railway driving simulator with eye tracker. The given driving scenario was a multi-task scenario in which the main task was to stop the simulated train before a ground device malfunction. The important sub-task was to recognize an extraordinary event, which was a subsidence of railway track on their right. Participants who stopped the simulated train before passing the subsidence were identified as part of the Recognizing Group; participants who passed the subsidence were identified as part of the Non-recognizing Group. Visual behaviors of both groups were analyzed. The findings revealed that total of gaze duration in ahead area by the Recognizing Group was longer than that by the Non-recognizing Group. Each gaze duration in ahead area by the Recognizing Group was also longer than that by the Non-recognizing Group. [ABSTRACT FROM AUTHOR]
運転中に前方に発生する異常事象をいかに素早く発見するかに着目すると, 運転士の注視行動(注視 対象物や注視時間) のあり方が重要だと考えられる. 本研究では, 異常事象発見のための有効な視覚探 索方略を明らかにすることを目的とした• 鉄道事業者の現役の運転士121名を対象に, 視線検知装置付 き運転シミュレータを用いた実験を行った. 運転シナリオは二重課題とした•メインタスクは事前に知 らされた地上設備故障の手前で一旦停止する課題, サブタスクは約90 km/hで走行中に事前に知らされ ていない隣接線の陥没を発見し停止するという課題であった.陥没箇所を発見し通り過ぎる前に停止し た運転士を「発見群」, 陥没箇所を通り過ぎた運転士を「非発見群」と分類した•運転士の注視行動を分 祈した結果, 発見群は非発見群と比較して, 前方正面の総注視時間が長く, -回あたりの注視時間も長 かった.
