1. A computer-implemented method for providing a description of a road segment, the method comprising:
- selecting two first location reference extension points to identify a road that includes the road segment, wherein a first point of the two first location reference extension points corresponds to a first location along the road and a second point of the two first location reference extension points corresponds to a second location along the road;
determining a first distance between the first point and the road segment and a second distance between the second point and the road segment;
selecting, based on the first distance and the second distance, two second location reference extension points to identify a portion of the road that is located between the first location and the second location, wherein the portion of the road includes the road segment;
generating, via a processor, the description of the road segment based on the two first location reference extension points and the two second location reference extension points, wherein the description identifies the road using the two first location reference extension points and identifies the road segment using the two second location reference extension points;
generating a textual output of the road segment based on the description; and
causing the textual output to be outputted to a display.

Abstract
A system provides a description of a road segment using location reference points. The system may receive traffic information about a road segment along a road. The system may determine two sets of location reference points based on the traffic information. The system may generate a description of the road segment based on the two determined sets of location reference points.

11. A system for generating a description of a road segment, the system comprising:
-
a receiver configured to receive information about the road segment; a processing unit configured to; determine two first location reference extension points identifying a road that includes the road segment, wherein a first point of the two first location reference extension points corresponds to a first location along the road and a second point of the two first location reference extension points corresponds to a second location of the road, determine a first distance between the first point and the road segment and a second distance between the second point and the road segment; and determine, based on the first distance and the second distance, two second location reference extension points identifying a portion of the road that is located between the first location and the second location, wherein the portion of the road includes the road segment; and a message generating unit configured to; generate the description of the road segment based on the two first location reference extension points and the two second location reference extension points, wherein the description identifies the road using the two first location reference extension points and identifies the road segment using the two second location reference extension points, and generate a textual output of the road segment based on the description. - View Dependent Claims (12, 13, 14, 15)

16. A receiving device configured to alert a user about a traffic event on a road segment, the receiving device comprising:
-
a receiving unit configured to receive a message, the message comprising; two first location reference extension points identifying a road that includes the road segment experiencing the traffic event, wherein a first point of the two first location reference extension points corresponds to a first location along the road and a second point of the two first location reference extension points corresponds to a second location along the road, and two second location reference extension points identifying a portion of the road that is located between the first location and the second location, wherein the portion of the road includes the road segment, and the two location reference extension points are determined based on a first distance between the first point and the road segment and a second distance between the second point and the road segment; a decoder configured to decode the received message and extract the two first location reference extension points and the two second location reference extension points; and an information unit configured to; generate a description of the road segment based on the two first location reference extension points and the two second location reference extension points, wherein the description identifies the road using the two first location reference extension points and identifies the road segment using the two second location reference extension points, and generate a textual output of the road segment based on the description. - View Dependent Claims (17, 18, 19)
