Abstract: A method, apparatus and computer program product are provided in order to identify a bi-modality condition upstream of diverging downstream road segments. In the context of a method, a distribution of speeds associated with a plurality of probe points representative of travel along the road segment upstream of diverging downstream road segments is determined. The method also includes evaluating the distribution so as to cluster the speeds associated with the plurality of probe points into a higher speed cluster associated with a higher speed and a lower speed cluster associated with a lower speed. The method also includes identifying a bi-modality condition upstream of the diverging downstream road segments based upon a relationship between the higher speed and the lower speed. The method further includes determining an extent to the bi-modality condition upstream of the diverging downstream road segments.

Abstract: A method, apparatus and computer program product are provided to identify a split lane traffic location. In a method, a distribution of speeds associated with a plurality of historical probe points representative of travel along a road segment upstream of diverging downstream road segments is determined for each of a plurality of epochs. For each epoch, the distribution is evaluated to cluster the speeds associated with the plurality of historical probe points during the respective epoch into higher and lower speed clusters. For each epoch, it is determined whether a bi-modality condition exists upstream of the diverging downstream road segments based upon a relationship between the higher speed and the lower speed during the respective epoch. A split lane traffic location is then identified based upon a bi-modality frequency with which a bi-modality condition is determined from the historical probe points associated with the plurality of epochs.
