Abstract
Methods and apparatuses are provided for generating, using, and storing ambiguity ratings for map matching. In an embodiment, an ambiguity rating is generated using a road segment and a relationship of the road segment and other nearby road segments. The ambiguity rating may be stored in a cell based map. The ambiguity rating may be used to select an efficient map matching algorithm and provide expected map matching confidence.
