Abstract: The amount of traffic on the road is greatly affected by both an inter-vehicle distance and a vehicle speed. When the amount of traffic increases and is more than a threshold value, an ECU 20 and an ACC 30 control the inter-vehicle distance and the vehicle speed such that the amount of traffic is a predetermined value equal to or more than the threshold value. In this way, it is possible to effectively suppress traffic congestion.

Abstract: A navigation system acquired information relating to a point, such as a sag where a decrease in vehicle speed is induced in front of a system-mounted vehicle. When the system-mounted vehicle has reached a predetermined distance from the sag concerning the information acquired by the navigation system or when a predetermined time has come before reaching the sag, an ECU and an ACC controls the traveling of the system-mounted vehicle such that the inter-vehicle distance from an ordinary vehicle behind the system-mounted vehicle increases. Therefore, even when a vehicle control device is not mounted in an ordinary vehicle behind the system-mounted vehicle, it becomes possible to prevent a decrease in the speed of the ordinary vehicle behind the system-mounted vehicle, thereby more effectively suppressing congestion.
