Abstract
An approach is provided for generating road curvature data. The approach, for example, involves map matching location trace data to a road network, wherein the location trace data is associated with ground truth curvature values. The approach also involves dividing the road network into a plurality of bounded areas (e.g., boxes or other shapes). The approach further involves extracting one or more training features for each bounded area of the plurality of bounded areas from the location trace data map matched to said each bounded area. The approach further involves training a machine learning model based on the one or more training features and ground truth curvature values. The approach further involves providing the trained machine learning model to predict the road curvature data.
