Abstract: An approach is provided for a localized link-centric metric for directional traffic propagation. The approach, for instance, involves designating a base link of the road network. The approach also involves determining a plurality of vehicle trajectories that pass through the base link. The plurality of vehicle trajectories is based on probe data collected from one or more sensors of a plurality of vehicles travelling in the road network. The approach further involves determining a frequency at which the plurality of vehicle trajectories passes through the base link to each of one or more other links in the plurality of vehicle trajectories within a proximity threshold. The approach further involves computing a link-centric metric for said each of the one or more other links relative to the base link based on the determined frequency.
