A travel track creation device that creates a travel track on which a vehicle travels on a road which includes an inlet straight portion , an arc portion continuous to the inlet straight portion , and an outlet straight portion continuous to the arc portion , the travel track creation device comprising: a travel track creator that creates the travel track including an inlet straight track separated from an outer edge of the inlet straight portion by a predetermined distance toward a center side of the arc portion , an inlet clothoid track continuous to the inlet straight track and formed by connecting a first group of clothoid curves, an arc track continuous to the inlet clothoid track , an outlet clothoid track continuous to the ark track and formed by connecting a second group of clothoid curves, and an outlet straight track continuous to the outlet clothoid track and separated from an outer edge of the outlet straight portion by a predetermined distance toward the center side of the arc portion , wherein the travel track creator includes an arc creator that creates the arc track which is located further on a side opposite to the center side of the arc portion than a passing target point (P131) and has a maximal radius, the passing target point (P131) being separated from an inner edge of the arc portion by a predetermined distance toward the side opposite to the center side of the arc portion; and a clothoid creator that creates the inlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and a start point of which is in contact with the inlet straight track and in which a direction angle of the start point corresponds to a direction angle of the inlet straight track, and the outlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and which is in contact with the outlet straight track and in which a direction angle of a start point corresponds to a direction angle of the outlet straight track . a travel track creator that creates the travel track including an inlet straight track separated from an outer edge of the inlet straight portion by a predetermined distance toward a center side of the arc portion , an inlet clothoid track continuous to the inlet straight track and formed by connecting a first group of clothoid curves, an arc track continuous to the inlet clothoid track , an outlet clothoid track continuous to the ark track and formed by connecting a second group of clothoid curves, and an outlet straight track continuous to the outlet clothoid track and separated from an outer edge of the outlet straight portion by a predetermined distance toward the center side of the arc portion , wherein the travel track creator includes an arc creator that creates the arc track which is located further on a side opposite to the center side of the arc portion than a passing target point (P131) and has a maximal radius, the passing target point (P131) being separated from an inner edge of the arc portion by a predetermined distance toward the side opposite to the center side of the arc portion; and a clothoid creator that creates the inlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and a start point of which is in contact with the inlet straight track and in which a direction angle of the start point corresponds to a direction angle of the inlet straight track, and the outlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and which is in contact with the outlet straight track and in which a direction angle of a start point corresponds to a direction angle of the outlet straight track . <EOS>
