A segment determination device is provided with an altitude information acquisition unit that acquires altitude information about a plurality of points on a road on which a vehicle travels, a feature amount determination unit that determines a feature amount indicating gradient information about the road based on the altitude information about points including a first point ahead of the vehicle in a traveling direction of the vehicle and a second point further ahead of the first point among the plurality of points, and a segment determination unit that, in a case where the feature amount is outside of a predetermined range, determines a segment in which the first point is set as a start point and whichever of two points adjacent to the second point that is closer to the vehicle is set as an end point.
