Structure

• Three different approaches for network monitoring
• FVD Pilot Wales
• FCD Study Bavaria
• Results

Approach I

• Unit that collates and sends (ITIS FVD)
• Speed and Position
• Needs GSM and GPS only
• Total data coverage
• Historic data, forecast
• Real time data depends on SMS costs

4
Approach II

• Low end unit - high end radio
• Calculates independently, includes detection
  algorithms
• Needs GPS and GSM, but also algorithms
• Real time data cheap
• Only incident data
• Loss of GPS signal, loss of data, no map matching

5
Approach III

• High end unit
• vehicle sensors, vehicle bus, digital map,
  navigation, detection algorithmson-board
  analysis of FCD
• Needs GPS and GSM, vehicle bus
• Real time data cheap
• Only incident data
• Extended floating vehicle data (XFCD)wipers,
  hazard warning lights, fog lights,road surface

Results

• FVD Pilot Wales
• FVD is similar in quality to loop data
• Volume is smaller
• Data not at a fixed point
• M4 loop coverage very good
• Strength of FVD in Wales where no loops exist
• Good picture of entire network
