Abstract: The present disclosure provides a method for generating road topology information performed by at least one processor. With respect to coordinate data of a road, boundary conditions between segments including topology information may be calculated to make the connection between segments flexible, and a midpoint of a curve of a segment may be detected to directly calculate control points of a Bézier curve, thereby generating a parametric Bézier curve. Accordingly, more precise road map may be generated even when the coordinate data of the segment of the road includes an error.
