Rapid growth in the volume of freight transport has placed a tremendous burden on German motorways. This has resulted in increased investment requirements for maintenance and expansion.
Using a PPP ( Public Private Partnership) model for upgrading five highly loaded motorway sections, private companies have to perform upgrading, operation and maintenance within a 30 year concession contract. Project financing is based on the distance-based truck toll for all heavy vehicles with a permissible total weight of 12 tons or more.
Pöyry was commissioned by one of the bidding consortia to carry out traffic studies for five motorway upgrading projects. The target was to analyse and forecast the traffic volume of the heavy vehicles over 12 tons on these motorway sections.
The traffic studies consist of a detailed analysis and forecast of the structure of the vehicle fleet according the German toll classes (number of axles and emission classes). The outcome of the traffic study formed the basis of the revenue forecast for the financial offers of the bidding consortium.
