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.
