Traffic-Count Calculator

The Traffic-Count Calculator dialog on the Extras menu enables to redistribute the actual numbers of trains or of flight movements/APU-operations (i.e. traffic counts) for the time periods Day/Evening/Night.

Note

Regarding the application to air routes or to APU-operations see the manual to CadnaA-option FLG.

Especially with calculations according to the EC-Directive on Environmental Noise the prevailing numbers of trains or flights for Day and Night may be redistributed to the three time periods Day/Evening/Night. The variables for the traffic counts of the three time periods are: nd for Day, ne for Evening, and nn for Night.

The redistribution can be applied to:

  • all activated objects „Railway“,
  • all lists for „Numbers of Trains“ (and consequently for all objects „Railway“ referencing a respective train list), and
  • all active air routes,
  • and/or to all active APU-operations.

Example

In the example above, the actual traffic counts of the local train lists for Day and Night will be redistributed, resulting in Evening counts being 25% of the Day, plus 20% of the Night. Therefore, the original traffic counts are reduced for the Day to 75% and for the Night to 80%.

Option „Delete All-Zero-Lines“

When this option is active, all data sets of the selected object type/s containing no data (empty or zero lines) will be deleted upon the next recalculation. This option ensures that non-valid traffic data (e.g. from import operations) is kept and exported afterwards.

Option „Normalize Aircraft Classes“
