Sieber-Stauindex

The flourishing economy and population growth are leading to a steady increase in traffic congestion on the Swiss road network. This is also reflected in the congestion statistics from FEDRO (Federal Roads Office). The challenging traffic load has a direct impact on the Sieber truck fleet, for example:

• Significant loss of productivity due to vehicles stuck in traffic jams
• Factoring in larger time margins for fixed delivery deadlines
• Higher fuel consumption due to increased stop-and-go traffic

For these reasons, the Sieber Group charges an industry-standard congestion surcharge for the additional costs incurred. The congestion hours are calculated by Viasuisse AG on behalf of the Federal Roads Office FEDRO and published annually in the annual report “Traffic development and availability of the motorways”. Viasuisse now provides the congestion hours on a monthly basis. For this reason, the Sieber Group will now also update and calculate the congestion surcharge once a month.

Calculation of the congestion index

• The basis for the calculation is the sum of the congestion hours of the last 12 months (rolling calculation)
• The congestion surcharge is adjusted and published on a monthly basis
• The congestion zone lower limit of 0% is not undercut
