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.
