An intersection visibility determination device includes an ECU that determines visibility at an intersection. When a host vehicle approaches an intersection with a stop sign, the ECU calculates conflict points at which a trajectory vector of the host vehicle intersects with virtual trajectory vectors of intersecting objects, which are presumed to come from the right side and the left side of the intersection, respectively. The conflict points are calculated based on information on types and traveling positions of the intersecting objects. The ECU sets visibility determination areas at the intersection as viewed from the host vehicle based on the positions of the conflict points, the right-side and the left-side visibility target distances, and the current location of the host vehicle, and calculates, based on the visibility determination areas, visibility distances that are used as visibility parameters indicating whether the visibility at the intersection is good or poor.
