confidence property

double? confidence

The confidence field indicates the proportion of real-time data included in the speed calculation. It is a normalized value between 0.0 and 1.0 with the following meaning:

  • 0.7 < confidence <= 1.0 indicates real time speeds
  • 0.5 < confidence <= 0.7 indicates historical speeds
  • 0.0 < confidence <= 0.5 indicates speed limit

This field can be used to identify whether the data for a location is derived from real-time probe sources or historical information only. All confidence data 0.71 and above is based on real-time information, where a confidence value of 0.75 or greater indicates high confidence real-time information. A confidence value equal to 0.70 or lower means that the data is derived from historical data only. Gets the confidence field value which is normalized value between 0.0 and 1.0.
