A segment determination device has an altitude information acquisition unit that acquires altitude information about points on a road, and 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 a vehicle and a second point ahead of the first point. The altitude information acquisition unit acquires altitude information about another points farther from the vehicle until the determined feature amount is outside of a predetermined range. The segment determination device further has a segment determination unit that, in a case where the feature amount is outside of the 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.
