摘要

It is determined whether or not the previous travel frequency, i.e., the number of times that a vehicle has previously traveled a road intersecting a stored no-signal intersection, exceeds a pre-set previous travel determining frequency, and if the road for which the previous travel frequency was determined to exceed the previous travel determining frequency is determined to be a non-priority road, then the stopping target position is set on the basis of travel information of only the vehicle for which the previous travel frequency was determined to exceed the previous travel determining frequency, and if the road for which the previous travel frequency was determined not to exceed the previous travel determining frequency is determined to be a non-priority road, then the stopping target position is set on the basis of travel information of multiple vehicles including the vehicle for which the previous travel frequency was determined to not exceed the previous travel determining frequency.
