MAP-CENTRIC MAP MATCHING METHOD AND APPARATUS

A method, apparatus and computer program product are provided to process probe data in accordance with a map-centric map matching technique. In the context of a method, a plurality of vertices are defined along a polyline representative of a road segment such that the polyline includes one or more edges. Each edge extends between a pair of neighboring vertices. For each vertex of a respective edge, spatial searches are conducted to identify each probe point within a region about a respective vertex. For each probe point identified within a region about a respective vertex, a determination is made as to whether the probe point satisfies a projection criteria in order for the probe point to be projected onto the edge or one of the neighboring vertices between which the edge extends.
