Abstract
An unexpectedness prediction sensitivity determining apparatus determines a standard driving operation level of a driver when turning to the right or left at an intersection for each intersection based on intersection travel information received from plural vehicles. Subsequently, the unexpectedness prediction sensitivity determining apparatus determines the unexpectedness prediction sensitivity of the driver when turning to the right or left at the intersection based on the intersection travel information associated with the intersections where determined standard driving operation levels of the drivers are identical to one another.
