Evaluation Method of the Driving Workload in the Horizontal Curve Section Based on the Human Model of Information Processing.

The aim of this study was to quantify the effect of radius over horizontal curve sections on driving workload (). Twenty-five participants participated in the driving simulation experiments and completed five driving scenes. The NASA-TLX scale was used to measure the mental demand, physical demand, and temporal demand in various scenes, which were applied to assess subjective workload ().
