Method, apparatus, and computer program product for generating turn paths through an intersection

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions to:

• receive probe data from a plurality of probes passing through an intersection;
• identify a turn maneuver of the intersection including an incoming road link and an outgoing road link;
• generate a curve of the turn maneuver based on a geometry of the intersection and a scaling factor;
• filter the probe data by map-matching the probe data to the generated curve with at least one predetermined tolerance based on a placement and shape of the curve to obtain remaining probe data, wherein the map-matched probe data is the remaining probe data;
• fit a spline to the remaining probe data to generate a turn path representative of the turn maneuver;
• and
• provide for guidance of a vehicle based on the spline of the turn path.
