  "textContent": "A navigation system, method, apparatus and computer program product process probe data utilizing map-centric map matching. In a method, the grid cell in which the probe point is located is determined from among a plurality of grid cells of a region. The method also projects the probe point onto a road center polyline segment associated with the grid cell. The road center polyline segment extends through a map matching road region having edges that are spaced apart from a road center of a road segment by a predefined distance such that a probe point inside a grid cell that is intersected by or included by the map matching region associates the probe point with the road center polyline segment and thereby with road segment as well. Traffic estimation and route guidance may be provided based upon the association of the probe point with the road segment.",
