Abstract
The present application belongs to the field of intelligent transportation technology, and in particular to a high-precision spatio-temporal trajectory recovery method based on cell phone signaling data, using a density clustering algorithm to pre-process original cell phone signaling data, using a grid clustering algorithm that fuses spatio-temporal features, introducing POI data from Baidu maps, and carrying out a clustering analysis from the spatio-temporal two dimensions, extracting a plurality of staying points of the signaling user, and then reconstructing a signaling user's travel trajectory based on the staying points, the method provided by the present application enables the user's reconstructed trajectory to have a higher degree of precision, and is more closely fitted to the user's real trajectory.
