Iwasa, T. and Hashimoto, T., "ERRATUM: Study of Reproducibility of Pedal Tracking and Detection Response Task to Assess Driver Distraction," SAE Int. J. Trans. Safety 5(1):133-134, 2017, doi:10.4271/2015-01-1388.01.
1. On page 111, the authors have described a method to assess driver distraction. In this method, participants maintained a white square size on a forward display by using a game gas pedal of like in car-following situation. The size of the white square is determined by calculating the distance to a virtual lead vehicle. The formulas to correct are used to explain variation of acceleration of the virtual lead vehicle. The authors inadvertently incorporated old formulas they had used previously. In the experiments discussed in the article, the corrected formulas were used. Therefore, there is no change in the results. The following from the article:
