On Map-Matching Vehicle Tracking Data

  title={On Map-Matching Vehicle Tracking Data},
  author={Sotiris Brakatsoulas and Dieter Pfoser and Randall Salas and Carola Wenk},
Vehicle tracking data is an essential “raw” material for a broad range of applications such as traffic management and control, routing, and navigation. An important issue with this data is its accuracy. The method of sampling vehicular movement using GPS is affected by two error sources and consequently produces inaccurate trajectory data. To become useful, the data has to be related to the underlying road network by means of map matching algorithms. We present three such algorithms that… CONTINUE READING
