The evaluation exercise was structured into four stages (Fig. 2). The use of different research tools allowed us to validate and cross-check the evidence in accordance with triangulation principles. These included: (i) extensive desk research that collected information on developments in the area of road infrastructure safety management along with information on relevant practices across the different EU countries, (ii) a Member States and Stakeholder survey that provided a comprehensive understanding of the way in which the procedures are implemented, (iii) a Stakeholder workshop to validate the preliminary results and findings attained in the evaluation and, finally, (iv) an interview program that provided an appropriate range of additional information and evidence to support the identification of the main evaluation findings and the development of main conclusions and recommendations.
