A map information storage unit (12) that stores map information, a region determination unit (14) that acquires observed position information indicating observed positions at which an object is observed from a plurality of sensors, and determines whether each observed position is in any one of regions into which an area indicated by the map information is divided, a road reference position conversion unit (15) that converts each observed position determined to be in the region of the map information, into a traveling direction position indicating a position in a direction parallel to an assumed road direction in the region, and a transverse direction position indicating a position in a direction perpendicular to the assumed road direction in the region, using the map information, and a comparison unit (17) that rearranges the observed positions in order of the traveling direction, creates pairs of front and rear observed positions in the traveling direction, calculates a difference in the traveling direction positions and a difference in the transverse direction positions between each pair of observed positions, and determines that a pair of observed positions between which the differences are within thresholds specified in respective items are derived from the same object, and determines that a pair of observed positions between which at least one of the differences is greater than the threshold are derived from different objects, are included.
