The vehicle information acquisition unit (11) acquires vehicle information regarding travelling states of vehicles that are present in the vicinity of a plurality of respective intersections from data received from each of a plurality of detection apparatuses (20). The congestion determination unit (13) determines, for each of the plurality of intersections, whether congestion is occurring based on the vehicle information and determines an intersection where congestion has occurred to be a congested intersection. The intersection specifying unit (15) specifies, when there is a continuous congestion path including a plurality of consecutive congested intersections, a congestion-inducing intersection, which is an intersection that has induced congestion in a continuous congestion path. The cause determination unit (14) specifies the cause of the congestion occurred in the congestion-inducing intersection.
