Study on Subsidiary-Task Procedure to Assess Driver Distraction

This study discusses appropriate performance-measurement task configurations for subsidiary-task procedures to determine the influence of in-vehicle human interface tasks on driver distraction. Steering-wheel tracking (ST), pedal tracking (PT), and visual detection (VD) tasks were examined as candidate tasks to be performed along with the assessed tasks in a laboratory situation. The results revealed that PT was a superior performance-measurement task in terms of the sensitivities among the assessed task differences, and its performance measure (deviation ratio) was consistent with its impact on actual driving behavior (variability of vehicle lateral displacement and headway distance). The merits of the PT task used in the subsidiary-task procedure are discussed in terms of the operational modalities and cognitive demands underlying task predictability.
