Abstract
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.
