A paper titled ‘Needs and priorities of road safety stakeholders for evidence-based policy making‘ co-authored by Eleonora Papadimitriou and George Yannis is now published in Transport Policy Journal. The objective of this research is the analysis of needs and priorities of road safety stakeholders for evidence-based policy making. Needs and priorities concern both the data to be collected or made available and the tools to be developed or made available to support science-based policy-making. Within the EC co-funded DaCoTA research project, an on-line survey was addressed to more than 3.000 stakeholders, mostly from European countries, in which participants were asked to assess the importance of more than 50 items reflecting data and resources for all stages of road safety policy making. Cluster analysis was carried out, revealing 4 groups of stakeholders with similar needs and priorities: a “low priorities” group, a “need data and models group”, a group mainly interested on “implementation” and an “in-depth analysis” group. Further analysis suggested that the four clusters are adequately – and often similarly – represented in all groups of countries, and in all types of organizations (e.g. national administrations, universities, interest groups, road safety organizations etc.).
