A method is provided for establishing lane-level speed profiles for road segments and strands of road segments based on historical vehicle probe data. Methods may include: receiving a plurality of probe data points, where a sequence of probe data points from a respective probe apparatus defines a trajectory of the respective probe apparatus; map-matching trajectories of the plurality of probe apparatuses to lanes of a road segment of a road network; determining, from each trajectory of the plurality of probe apparatuses to lanes of a road segment of a road network; determining, from each trajectory of the plurality of probe apparatuses map-matched to the lanes of the road segment, average path speeds along each lane of the road segment; clustering the aggregated speeds on each lane into a predetermined number of speed profiles using a clustering technique; and generating a lane-level speed profile for the road segment.
