                         TEN-STAC: Scenarios, Traffic forecasts and Analysis of Corridors on the Trans-European network.






Project Funding

The TEN-STAC project was funded by the European Commission (DG Transport and Energy).





Project summary

The TEN-STAC project was performed to facilitate the TEN-T revision process carried out by the European Commission in the period of time 2002-2004. Thus, the main tasks of the project were

  • to provide a common understanding framework by the development and assessment of European TEN-T scenarios and traffic forecast;
  • to develop and apply an analytical basis for the “corridor approach”;
  • to provide a framework for an homogeneous assessment of TEN-T projects;
  • and to better anticipate the financial consequences of the selection of priority projects, notably on the Community budget.

The project was split in two phases, phase I and phase II.

Phase I included

  • the computation of traffic forecasts for the forecast year 2020, including traffic assignment, estimation of international traffic load on the network, emissions and regional accessibility impacts for three different infrastructure scenarios;
  • a review of national transport infrastructure plans, and macroeconomic analysis to estimate potential public financing in transport infrastructure until 2020;
  • the development of a generic definition of multimodal corridors, building on the Pan-European Corridors, including motorways of the sea and dedicated rail freight axes.

Phase II embraced

  • the development of a strategic assessment framework for the application to individual projects within corridors, and the development of a methodology to ease implementation;
  • the assessment of 72 priority projects on 22 corridors according to 39 assessment variables of the domains economic impacts in the transport sector, environmental sustainability, investment cost, general transport relevance, creation of European value added, improvement of accessibility, as well as maturity and coherence of the project;
  • broad financial assessment of priority projects with preliminary indication of type and level of risks and share of public and private financing;

Transport demand and impacts of the domains environment, economy and accessibility were computed under application of the VACLAV/ NEAC modelling platform.

IWW's main responsibilities were the generation of passenger demand forecasts and the assignment of passenger and freight flows. Furthermore, IWW was largely involved in the assessment of the three phase I investment scenarios with regard to economic, environmental, and centrality criteria, as well as congestion, and contributed to the identification of important trans-national transport corridors. For the purposes of phase II,  IWW developed and applied an efficient methodology for the computation of transport-related impact data for each of the 72 priority projects.
