A reference identification unit identifies a target reference position to be a reference from a position history indicated in target information, based on a movement state of a target object, and identifies a nearby reference position to be a reference from a position history indicated in nearby information, based on a movement state, estimated from the nearby information, of a nearby object which is a mobile object present in the vicinity of the target object. A position estimation unit estimates a relative position between the target object and the nearby object, based on the target reference position and the nearby reference position.
