Prequels (Traffic NO2 Overlay)

From Tygron Support wiki
Jump to: navigation, search

Prequel overlays can be linked to the Traffic NO2 Overlay to base traffic intensities for calculations on, rather than basing it on roads and their Attributes in the 3D World.


Notes

  • A Prequel with a single timeframe will mean that value applies to all hours of the day. A Prequel with multiple timeframes is assumed to have 24 timeframes, with each timeframe representing a single hour of the day.
  • In case a prequel is selected for a particular traffic type, the jam factor is still obtained from the existing roads, just as when no prequel is provided. The prequel only provides an alternative value for the number of traffic for that traffic type.
