A travel track creation device (2) includes a travel track creator (42) that creates a travel track including an inlet straight track, an inlet clothoid track formed by connecting a first group of clothoid curves, an arc track, an outlet clothoid track formed by connecting a second group of clothoid curves, and an outlet straight track, wherein the travel track creator (42) includes an arc creator (42a) 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 and a radius of which is as large as possible, the passing target point 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 (42b) 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.
