Abstract: A road surface marking detection means detects a road surface marking on a road, based on sensor information acquired by sensing a road. An interruption detection means detects a portion where the road surface marking is interrupted, based on a detection result of the road surface marking. A factor determination unit determines a factor for which the road surface marking is interrupted with respect to a portion where a matter that the road surface marking is interrupted is detected.
