摘要
A curved-section-information supplying apparatus includes: a clothoid-section identifying unit that identifies a clothoid section included in a curved section of a road; a clothoid-coefficient obtaining unit that obtains a clothoid coefficient for a clothoid curve representing a shape of the clothoid section identified by the clothoid-section identifying unit; and a radius-of-curvature calculating unit that calculates a radius of curvature at a position at a travel distance in the clothoid section, based on the clothoid coefficient and a curve length from a start point of the clothoid curve, the curve length corresponding to the travel distance from a start point of the clothoid section, to supply curved-section information based on the radius of curvature at the position at the travel distance in the clothoid section.
