Benefits
Benefits

• Technical Performance
• Mobile Journey Time System
• Trials over several peak periods to verify
  correlation of journey times (FVD vs MJTS) at the
  95 confidence interval
• Hit (read) rate of ANPR over 60
• Outlier results must be removed for accurate
  Journey Times
• 14 of Plates successfully matched over a long
  section of route to provide journey times (NB
  ANPR on inside lane only)
