Update on investments in large TEN-T projects : study

This study updates the TEN-T investment study completed in early 2013 and adds five new case studies to the analysis, three of which deal with mega projects that are still in the planning or early implementation phase: Lyon-Turin, Iron-Rhine and S21/Stuttgart-Ulm. Findings confirm that not all stakeholders have learned past lessons on successfully developing projects. There is a particular need for early and transparent public participation and a clear project definition prior to the project decision. New findings suggest that measuring wider economic benefits and European added value are necessary to justify the socio-economic benefits of multibillion euro cross-border projects.
