A method for characterizing the curvature of a road section, including: selecting, from among the points of the section, the points marking a curvature of the section; computing, for each selected point of the section contained between the second and the penultimate one, an indicator of curvature of the section at this point; identifying each bend contained in the road section, each bend including a set of successive selected points of the section; and for each bend contained in the road section, comparing the indicator of curvature of at least one of the points of the bend with a predetermined threshold. If the indicator of curvature computed for at least one of the selected points of the bend exceeds the predetermined threshold, recording, in a database, a data record including at least the set of points of the bend, and an item of data characterizing the curvature of the bend.
