Abstract
A method is provided, performed by at least one apparatus, the method including: obtaining probe data including a plurality of probe samples of a multi-dimensional probe sample space, the probe data being representative of a potentially multi-modal traffic scenario; performing a cluster analysis for at least a part of the probe samples of the probe data, the cluster analysis including: associating at least a part of the probe samples with respective clusters, each cluster being representative of a mode of the potentially multi-modal traffic scenario.
Claims20
A method, performed by at least one apparatus, the method comprising:
- obtaining probe data comprising a plurality of probe samples of a multi-dimensional probe sample space, the probe data being indicative of a multi-modal traffic scenario;
- performing a cluster analysis for at least a part of the plurality of probe samples of the probe data, said cluster analysis comprising:
- grouping at least the part of the plurality of probe samples with respective clusters, each cluster being indicative of a mode of the multi-modal traffic scenario;
- determining confidence information for a result of the cluster analysis based, at least in part, on a cluster distance between determined clusters;
- determining traffic information on a per-lane basis based on the respective clusters;
- and
- determining whether traffic information is to be relied upon based on the confidence information.
An apparatus, comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus to:
- perform a cluster analysis for at least a part of probe samples of probe data, said cluster analysis comprising:
- group at least the part of the probe samples with respective clusters, each cluster being indicative of a mode of a multi-modal traffic scenario;
- determine confidence information for a result of the cluster analysis based, at least in part, on a cluster distance between determined clusters;
- determine traffic information on a per-lane basis based on the respective clusters;
- and
- determine whether traffic information is to be relied upon based on the confidence information.
A computer program product comprising at least one non-transitory computer-readable storage medium having computer program code portions stored therein, the computer program code portions, when executed by a processor cause an apparatus to:
- perform a cluster analysis for at least a part of probe samples of probe data, said cluster analysis comprising:
- group at least the part of the probe samples with respective clusters, each cluster being indicative of a mode of a multi-modal traffic scenario;
- determine confidence information for a result of the cluster analysis based, at least in part, on a cluster distance between determined clusters;
- determine traffic information on a per-lane basis based on the respective clusters;
- and
- determine whether traffic information is to be relied upon based on the confidence information.
