A segment determination device has an acquisition unit for acquiring altitude information about points on a road on which a segment is defined, a calculation unit for calculating a distance between a point where a vehicle is located and an end point of the segment, a reference point determination unit for determining a reference point that is a point closest from the end point based on the calculated distance, a feature amount determination unit for determining a feature amount that indicates gradient information, and a segment determination unit for, in a case where the feature amount is outside a predetermined range, determining a segment in which the end point of the segment is set as a start point and whichever of two points adjacent to the point more ahead of the vehicle than the reference point that is closed to the vehicle is set as an end point.
