Claim:
1. A method comprising: traversing, by a first vehicle, a section of a road; continuously capturing, by at least one camera carried on-board the first vehicle during the traversing, images of the road; collecting, by a computer system carried on-board the first vehicle, global location information identifying a plurality of geographic locations of the first vehicle during the traversing; searching, by the computer system, the images for one or more visual indicators of one or more inductive loops embedded in the road; identifying, by the computer system within at least one image of the images, at least one visual indicator of a first inductive loop embedded in the road; using, by the computer system, relative location information identifying a relative location of the first inductive loop with respect to the first vehicle when the at least one image was captured and the global location information to determine a global location of the first inductive loop; and storing, by the computer system, the global location of the first inductive loop.
