Work conducted within REORIENT, a Sixth Framework project for the European Commission (EC), is described. One objective of REORIENT was to explain the status of transformation of the European railway sector into a functionally integrated, interoperable system. The status of interoperability within and between 11 countries in a corridor stretching from Greece to the Nordic countries was assessed, and conditions in the countries that appear to be barriers to achieving interoperability were identified. Barriers were defined as shortcomings in conditions that would facilitate the implementation of requirements presumed by the EC to lead to seamless international freight transport (implementation conditions). The primary data source for the analysis was a set of interviews with the major actors and stakeholders associated with each country's rail freight system. The qualitative information from the interviews was translated into numeric scores, which were subjected to statistical analysis. The objective of the statistical analysis was to provide an assessment of the relationships between the requirements and the implementation conditions. The statistical analysis involved both the identification of relevant relationships and an assessment of the strength of these relationships. A Barrier Significance Score (BSS) was computed for each country and for each implementation condition. These scores were used to assess the relative importance of barriers across the studied countries and to identify the most critical barriers to be removed in order to improve interoperability. Very large differences in BSSs were found between countries. In general, there are fewer barriers in Nordic countries and more barriers in the south.

Work conducted within REORIENT, a Sixth Framework project for the European Commission (EC), is described. One objective of REORIENT was to explain the status of transformation of the European railway sector into a functionally integrated, liberalized, interoperable system. The status of interoperability within and between eleven countries in a corridor stretching from Greece to the Nordic countries was assessed, and conditions in the countries that appear to be barriers to achieving the EC’s goals were identified. (Barriers were defined as shortcomings in conditions that would facilitate the implementation of requirements presumed by the EC to lead to seamless international freight transport (“implementation conditions”)). The primary data source for the analysis was a set of interviews with the major actors and stakeholders associated with each country’s rail freight system. The (qualitative) information from the interviews was translated into numeric scores, which were subjected to statistical analysis. The primary objective of the statistical analysis was to provide an assessment of the relationships between the requirements and the implementation conditions. The statistical analysis involved both the identification of relevant relationships and an assessment of the strength of these relationships. Overall, we found that there was considerable variation in interoperability status across the countries on practically all of the requirements. However, there was also considerable variation in the status of the implementation conditions across the countries. As a result, we found that most of the variability was able to be explained by relationships that were found to exist between the requirements and implementation conditions. A ‘Barrier Significance Score’ (BSS) was computed for each country and for each implementation condition. These scores were used to assess the relative importance of barriers across the countries, and to identify the most critical barriers to be removed in order to improve interoperability. Large differences in BSS’s were found among countries. In general there are fewer barriers in Nordic countries and more barriers in the south.

REIVON is a Clean Sky 2 Technology Evaluator project that investigates to what extent CO2 emissions of global aviation can be reduced via optimisation of aircraft size/range and flight network. Three alternative global flight networks are created, considering (1) splitting long-haul flights into shorter legs (intermediate stop operations, ISO), (2) reducing frequency to the necessary minimum on busy routes using larger aircraft, and (3) a combination of 1 and 2. In all cases, the use of aircraft optimised for specific combinations of range and seating capacity not existing today will be considered. For the first time, REIVON will carry out a holistic analysis of the impact of an optimised flight network on global air transport system stakeholders, such as passengers, aircraft manufacturers, airlines and airports, and of potential measures to support the implementation of such an alternative network.
