Mass GPS Tracking Data Compression Method Based on Road Features

    Graphical Abstract
    • Abstract
  • A storage and management method for GPS tracking data based on road features is proposed,considering that the car trajectories are road network constrained.The storage space is significantly reduced when only the information of road feature points is recoded and the 2-D geographic coordinates are transformed to linear referencing tags.With the advantage of less data redundancy,the road network associated tracking data can better support the further analysis and traffic information abstraction.
