る。With such a configuration, the main-line side vehicle sees the red area, and there is a merged vehicle at that location, and if you look at the yellow area and your vehicle is still in this range, the merged vehicle is at the merge point. It is judged that there is a risk of confusion with this, and as a result of trying to avoid this range by deceleration or escape, smooth merging becomes possible. On the other hand, on the merging vehicle side, the positional relationship between the main vehicle and the own vehicle becomes clear, and it is possible to avoid the main vehicle and merge. As a result, the effect of smooth merging is obtained.
