Abstract

An approach is provided for path-based map matching. The approach involves, for instance, executing a first pass map-matching process to determine on-road candidate matches for observation points of the trajectory. The approach also involves determining emission probabilities of the candidate matches and transition probabilities between on-road candidates of subsequent observations, and determining a most probable path based on the emission and transition probabilities. The approach further involves determining a set of a predetermined number of on-road candidate matches from the most probable path. The approach further involves marking at least one match in the set as not matched based on determining that an alternate transition with a higher transition probability than the at least one transition exists. The approach further involves redetermining the most probable path using a second pass map-matching process based on the marked match.
