An external environment recognition unit recognizes a construction section ahead of a host vehicle and recognizes that one or more recognition objects express entry possible/impossible information as to whether the host vehicle can enter the construction section. If the external environment recognition unit recognizes a traffic control person who directs traffic in the construction section as the recognition object and recognizes the entry possible/impossible information that is expressed by the traffic control person, an action plan unit (or an entry determination unit) decides whether to cause the host vehicle to enter the construction section or to stop before the construction section by using preferentially the entry possible/impossible information that is expressed by the traffic control person.
