1. A method for creating a digital representation of a transportation network, the method comprising:
- refining acquired probe traces based on characteristics of the transportation network, the probe traces being a plurality of sequential location measurements from a plurality of devices;
identifying geographic objects associated with the transportation network based on the refined probe traces;
building a digital geographic network based on the refined probe traces and identified geographic objects; and
creating the digital representation of the transportation network by linking the identified geographic objects in the digital geographic network.

Abstract
In a method for creating a digital representation of a transportation network, acquired probe traces are refined based on characteristics of the transportation network. Geographic objects associated with the transportation network are identified based on the refined probe traces. A digital geographic network is built based on the refined probe traces and identified geographic objects, and the digital representation of the transportation network is created by linking the identified geographic objects in the digital geographic network.
