  26. 26. Geographical and Meteorological Data Fusion Different geographical referenced (lamiary, punctiform, etc) Weather and Road Condition Data Sources with different actualization time schedules as well as event driven Data are processed to generate accurate high resolution Road Weather Information by means of a Data Fusion Matrix = Knowledge Base
  27. 27. Example of Service Data Output on Highways in Bavaria Messages coded in TMC ALERT-C Aquaplaning Slippery Ice Slippery Road Strong Wind Strong Precipitation
  28. 28. Example of an authentic situation 2005 April 19. 17:00 A96 / Oberpfaffenhofen ALERT-C Message: Precipitation
  29. 29. Quality management by means of XFCD observation tours Example: TF1b 28.03.2006 21:05 To meet the high requirements of a premium service, a constant, automatic quality measurement and evaluation takes place which is based on defined quality scores for message and service quality. For that purpose, data from surveying and probe collecting tours by XFCD vehicles from BMW are summoned.
