Abstract

An approach is provided for road curvature data. The approach, for example, involves segmenting a road segment or plurality of road segments into a plurality of slices. The approach also involves retrieving location trace data for the plurality of slice. The location trace data, for instance, is collected from one or more location sensors of a plurality of vehicles traversing the plurality of slices. The approach further involves computing respective curvatures for the plurality of slices based on the location trace data. The approach further involves providing the road curvature data for the road segment of plurality of road segments (e.g., comprising an intersection) based on the respective curvatures of the plurality of slices.
