Saturation flow report describes the number of passenger car units (PCU) in a dense flow of traffic for a specific intersection capacity and time of the traffic signals.

Read how to create a saturation flow report in this article.

There are multiple metrics defined in the Saturation Flow report:

  • Freeflow reading - each reading for saturation flow calculation

  • Start of full demand - start of the reading for saturation flow calculation

  • End of full demand - end of the reading for saturation flow calculation

  • Duration - duration of the reading for saturation flow calculation

  • Time gaps - minimum, maximum and average time gaps between the vehicles (in seconds)

  • Traffic Volumes - multi-modal traffic volumes in each of the readings

  • Total PCU - total passenger car units in each of the readings

  • Saturation Flow per Reading - saturation flow calculated in each of the readings

  • Total Saturation Flow - total saturation flow calculation for the selected lane

First page of the saturation flow report is the header with information about the camera, scene description, monitored interval and conditions for saturation flow calculation.

Next sheets contain the saturation flows for all selected movements separately. Tables with green colours represent the movements where at least 10 free flow intervals have been computed, orange labels are by outputs with lower number of free flow readings than 10. However, this variable can be adjusted to your needs. You can decrease the number of free flow readings e.g. when you video is quite short to generate 10 intervals.
