For some indicators, coupled vehicle journeys are counted proportionally. This means, that two vehicle journeys which are coupled, in the coupled section share the value of the indicator. The Excel file IndicatorAvailability.xls provides an overview of the indicators to which this applies. If indicators regard the coupled vehicle journeys only for certain network objects, this is additionally noted in a comment.
The following example illustrates the influence of couplings. Couplings are taken into consideration for service kilometers, for section service kilometers however, couplings are not taken into consideration.
