On behalf of the European Commission a Consortium of European institutes headed by NEA executed the TEN-STAC project in 2003-2004. The preliminary phase consisted of forecasts for interregional transport and traffic both for passengers and freight and by transport mode under three scenarios. The geographical area consisted of an enlarged Europe and included the new member states and the candidate countries Romania and Bulgaria. The Commission had at that stage identified more than 75 infrastructure projects on 30 corridors. In the second phase, the objective of the study was to calculate about 30 ratios for each of the projects varying from transport economic ratios to external ones. Most of which were related to freight transport as the main focus of the Commission on interregional land transport is on freight. One of the problems in calculating these ratios was the interdependence between the projects: some projects were in competition with each other while others were enforcing each other. The proposed paper describes how these interdependences were approached and the results achieved. Since the financial requirement for all the projects together exceeds the amount of money available in Europe, splitting the projects into several categories based on the stage of implementation is considered the most appropriate. The approach using all of the projects will be used for a sensitivity analysis to avoid competing project that influence the same flows both being chosen.
