[TASK] To provide a technology that can suppress the possibility that a driver unintentionally reaches an attention location that requires a determination as to whether or not to travel.
[MEANS FOR SOLVING THE PROBLEM] A scheduled travel route for guiding a vehicle to a destination location is acquired to provide guidance on the scheduled travel route. An along-the-way route to be followed in the case where the vehicle travels along the way is acquired. An attention location that requires a determination as to whether or not to travel is acquired. An intersection which is positioned between the attention location that is present on the along-the-way route and the vehicle and to which a road that can be traveled on without reaching the attention location other than the attention location that is present on the along-the-way route is connected is specified as a guide target intersection. Guidance on the guide target intersection is provided in the case where guidance on the scheduled travel route is not provided.
