摘要
An approach is provided for speed aggregation of probe data for high-occupancy-vehicle (HOV) or other road lanes. The approach involves, for example, determining a line that is parallel to a road segment and divides the road segment along a longitudinal axis. The approach also involves determining a spatial distribution of probe data collected from the road segment with respect to the line. The approach further involves clustering the probe data into a first cluster and a second cluster based on speed. The approach further involves assigning the first cluster to a first lane of the road segment, the second cluster to a second lane of the road segment, or a combination thereof based on the spatial distribution to output a bi-modality event (e.g., an HOV traffic event).
