Development of a Real-time Steering Entropy Method for Quantifying Driver’s Workload
運転者負荷定量化のためのリアルタイム・ステアリングエントロピ法 の開発
The steering entropy (SE) method has been proposed as an index for quantifying driving workload when performing a secondary task while driving. However, this method has certain limitations, including an inability to measure driver workload in real time. This presentation describes a newly developed real-time steering entropy (RSE) method, which improves the conventional SE method by incorporating a real-time measurement capability, and presents an evaluation of its practical utility. The results revealed that the RSE method can accurately detect various conditions in which the driver encounters high workload on driving.ステアリングエントロピ法は，優れた運転集中度計測手法であるが，実時間で計算できない課題があった．今回，実時間，かつ，実走行環境で計測可能な計算方法を考案した．運転行動データベースを用いたシミュレーション評価により，覚醒度低下やディストラクション等に起因する運転集中度低下状態の検出の可能性を検証した．
