Drivers’ Risk Management in Distracted Driving Conditions

ディストラクションを受けているときのドライバの リスクマネジメントに関する研究

The present study aims to clarify the effect of visual and cognitive distraction on drivers’ risk management in a carfollowing situation. The primary task consisted of following a lead vehicle at a constant headway while that vehicle changed speed according to a predefined rhythm. The secondary task, which involved using a surrogate user interface, consisted of four different tasks to assess interference with the driver’s risk assessment during driving. To achieve the objective, the authors measured driver’s objective and subjective risk assessments by conducting a field experiment on a test track using 36 participants. The results suggested that the smallest effects on driver’s risk management were for the auditory stimuli and verbal response. It could be required to develop human machine interface to minimize driver’s risk management and maximize safe driving state.二次タスクによるドライバのリスク評価を試みた.情報取得,認知負荷,負荷量を組み合わせた二次タスクを実験条件とした.見て情報取得するときTHWが短くなるリスクを回避する行動をドライバは選択していた.聞いて情報取得するときTHWへの影響は小さかったが,認知負荷が有るときアクセル開度変化を小さくしていた.
