Commuting track description method and system based on MR position and road GIS information

The invention discloses a commuting track description method and system based on MR position and road GIS information, and belongs to the technical field of commuting track description, and the method comprises the following steps: S1, road grid interpolation; s2, grid attribute identification; s3, obtaining a user commuting track description sample point; and S4, describing the commuting track of the user. According to the invention, effective road track sample points can be extracted; the reliability of commuting data is improved through accumulation of daily trajectories and screening of high-frequency grids as a basis for depicting the trajectories; for the missing part of track points, the track is effectively filled by utilizing road intersection information and road grid sequence information; and the obtained user commuting track can be effectively applied to the scenes of urban traffic planning, personnel flow analysis, epidemic prevention and control and the like, and the method is worthy of populari
