Abstract
A method may include receiving driving data from a plurality of vehicles within a sampling region. The driving data may include speeds, positions, and lane change activity of the plurality of vehicles. The method may further include determining speeds of the plurality of vehicles based on the driving data. The method may further include performing cluster analysis on the speeds of the plurality of vehicles. The method may further include determining whether the speeds of the plurality of vehicles comprise more than one cluster based on the cluster analysis. Upon determination that the speeds of the plurality of vehicles comprise more than one cluster, the method may include determining that lane-level traffic is present within the sampling region.
