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.
Claims25
A computer-implemented method for providing a description of a road segment using location reference points, the method comprising the steps of:
- providing two first location reference points configured to identify a road including a road segment, where a first point of the two first location reference points corresponds to a first location along the road and a second point of the two first location reference points corresponds to a second location along the road;
- providing two second location reference points configured to identify a portion of the road between the first location and the second location where the road segment is located;
- and
- generating, through the use of a processor, a description of the road segment based on the two first location reference points and the two second location reference points.
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 points identifying a road having a road segment, where a first point of the two first location reference points corresponds to a geographic object located at a first location along the road and a second point of the two first location reference points corresponds to a geographic object located at a second location of the road, the processing unit being further configured to determine two second location reference points identifying a portion of the road between the first location and the second location where the road segment is located;
- and
- a message generating unit configured to generate a description of the road segment based on the two first location reference points and the two second location reference points.
A receiving device configured alert a user about a traffic event on a road segment, the receiving device comprising:
- a receiving unit configured to receive a message containing two first location reference points identifying a road including a road segment experiencing a traffic event, where a first point of the two first location reference points corresponds to a geographic object located at a first location along the road and a second point of the two first location reference points corresponds to a geographic object located at a second location along the road, the message further containing two second location reference points identifying a portion of the road between the first location and the second location where the road segment is located;
- a decoder configured to decode the received message and extract the two first location reference points and the two second location reference points;
- and
- an information generating unit configured to generate a description of the road segment based on the two first location reference points and the two second location reference points, the information generating unit configured to output the description to a user of the receiving the device.
