1. A computer-implemented method, comprising: obtaining first and second positional data elements, the first and second positional data elements being associated with corresponding first and second times, the first time being subsequent to the second time; identifying a first route link corresponding to the first positional data element and a second route link corresponding to the second positional data element; determining, using at least one processor, whether the first route link and the second route link correspond to a common route link; and generating, using the at least one processor, a portion of a routing graph that includes the common route link, when the first route link and the second route link correspond to the common route link.

The method of claim 1 , wherein the first and second positional data elements specify longitudes and latitudes at corresponding ones of the first and second times.
