Abstract

This study aims to confirm the usefulness of adaptation of proactive braking intervention systems to the risk level of the driving environment for improving the reactive factors of acceptability. First, we develop prototypes of adaptive proactive braking intervention systems around non-signalized intersections on community roads. Then, to confirm the effectiveness of adaptation, we conduct user tests, in which 45 elderly drivers participate, on public roads. From comparisons between constant setting and adaptive setting, we confirm that the adaptive setting improves the reactive factors of acceptability, such as reduction in the feeling of impatience and strangeness.
