1. A method for determining features of a digital representation of a transportation network, the method comprising:
- acquiring a plurality of probe trace data for an area of interest;
determining a plurality of choke points in relation to the probe trace data, each of said choke points comprising a non-decision point falling between adjacent decision points in said probe trace data;
generating a plurality of maneuvers from said probe trace data, each of said maneuvers comprising a mean path of a plurality of probe trace data that traverse the same path between adjacent choke points; and
determining and storing features of the digital representation of the transportation network based on the plurality of maneuvers.

Abstract
In a method for creating a digital representation of a transportation network location measurement data is acquired, and a plurality of maneuvers between choke points are generated from the location measurement data. The digital representation of the transportation network is then created and stored based on the plurality of maneuvers.
