Abstract
Systems and methods for the detection and analysis of curvature data are described. A method includes: receiving position data of a vehicle turning maneuver along a portion of a roadway, where the position data includes measured position data collected by sensors of a vehicle while traversing the vehicle turning maneuver; associating the received position data with map data of the portion of the roadway; generating a spline based on the position data, the spline being a smooth curve representing the vehicle turning maneuver from a first road segment to a second road segment; identifying a segment of the spline containing a turning point of the vehicle turning maneuver, the turning point representing a change of a vehicle path from along the first road segment to along the second road segment; and determining a maximum curvature value for the identified segment of the spline.
