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
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
Approach III
• High end unit

• vehicle sensors, vehicle bus, digital map,
  navigation, detection algorithms
  on-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
