  1. 1. Advanced Road Weather Information Systems (ARWIS) Sensors, Systems, Solutions
  2. 2. SWIS Schleswig-Holstein Top-Down-Approach
  3. 3. Outstations / ARWIS Pole construction, vandalism-proofen installation
  4. 4. Road (runway) pavement sensors Active and/or passive and/or non-intrusive
  5. 5. MDSS (Management Decision Support System) Customized user-views and applications
  6. 6. MDSS (SmartView3) Standard MDSS, software providing optionally
  7. 7. Details Outstations / ARWIS Modular and extendable, pole installation or on foundation
  8. 8. Intelligent UMB Technology Power Supply Comm. Modem “ All in One” atmospheric measures “ All in One” road condition measures radio- or line- communication UMB Technology = modular = extendable = low power digital standard Interface with open protocol digital standard Interface with open protocol Intelligent sensors + transmitting modules + real-time-communication Modular and extendable
  9. 9. UMB atmospheric sensors <ul><li>Innovative present weather sensor (R 2 S) </li></ul><ul><li>microwave doppler radar . </li></ul><ul><li>- Type of Precipitation (Hail, rain, snow, drizzle, sleet) </li></ul><ul><li>- Intensity of Precipitation (mm/h) </li></ul><ul><li>Measurement of wind direction and wind speed ultra sonic = precise measurement without mechanical moving parts. </li></ul><ul><li>Measurement of air pressure </li></ul><ul><li>Protection shield and active ventilation for </li></ul><ul><li>Accurate measurement of air temperature and </li></ul><ul><li>Relative humidity . </li></ul><ul><li>Digital communication with open protocol Power supply in one cable </li></ul>
  10. 10. UMB pavement sensor IRS31 <ul><li>Innovative microwave radar measurement of waterfilm depth up to 4 mm - Resolution: 0,01 mm - = 10 micrometers (0.39 mil) </li></ul><ul><li>Passive Measurement of salt concentration and Freeze Temperature by means of conductivity in conjunction with waterfilm depth </li></ul><ul><li>Surface condition detection </li></ul><ul><li> capacity measurement  dry, damp, wet, freezing wet, critical </li></ul><ul><li>Surface Temperature and also 2 Sensor Interfaces for Subsurface Temperatures (5 cm and 30 cm) </li></ul><ul><li>Digital data communication Interface (RS485) with open protocol </li></ul>Maintenance friendly removable Sensor inlet Makes OEM solutions easy!

  24. 24. Added Values Info- and Call- Service Platform Intelligent Sensors RPU‘s Communication Customer-specific Central Computer Info System Software Service Providing Call-Service Road Winter Maintenance ARWIS Tailored Road Weather Information provided for Service-Providers Road Weather Service Operation Platform RWS-TTI Traveler and Traffic Information Service Provider Weather Service
  25. 25. XFCD (Extended Floating Car Data) Mobile Data Sources GPS GSM <ul><li>- Speed profile </li></ul><ul><li>- Sensor data </li></ul><ul><li>Road and driving </li></ul><ul><li>conditions </li></ul>Position Telematic Device with XFCD-Modul Extended means:
  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 Bayerninfo.de
  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.
