• an area category determination unit that determines a category of a portion of the travelable area among a plurality of categories including a category indicating there is insufficient three-dimensional shape information for a respective portion of the travelable area;
• a complementary portion determination unit that determines there is a complementary portion within the area which complements the travelable area based on portions of the travelable area and the category of the portions of the travelable area indicating there is insufficient three-dimensional shape information;
• and
