| Abstract(J) | 事業用自動車ドライバの居眠り事故低減を目的に，点呼後の運行中に覚醒度低下を検出し居眠りの発生を予測するシステム（DAPS）を構想．眠気に伴う作業記憶と発話能力の変化に着目し，これらを評価するテストを夜間反復して行う被験者実験を実施．眠気上昇に伴い成績低下が見られ，各テストで用いた指標の有望性を示した． Translation |
| Abstract(E) | We conceptualized a Drowsiness Assessment and Prediction System (DAPS) for commercial vehicle drivers to reduce drowsy-driving crashes by detecting declines in arousal during driving after the pre-duty roll call (tenko) and predicting the onset of drowsiness. Focusing on sleepiness-related changes in working memory and speech-related performance, we conducted an overnight, repeated-measures human-subject experiment in which tests assessing these functions were administered repeatedly. Test performance declined as sleepiness increased, demonstrating the promise of the indices used in each test. |
