Abstract
An approach is provided for providing a map matcher tolerant to wrong map features. The approach involves, for instance, finding a segment of a probe trajectory containing a plurality of low-speed probe points. The approach also involves forming a line between a first and a last probe point of the segment. The approach further involves calculating a distance from each probe point of the segment to the line. The approach further involves splitting the segment based on comparing the distance to a threshold at a turning point of the segment. The approach further involves creating a new probe trajectory based on a plurality of high-speed probe points in the probe trajectory and the turning point. The approach further involves estimating a heading of the turning point of the segment based on the new trajectory, and then performing a feasibility check between two consecutive probe points of the new trajectory.
