Abstract
The paper presents the study performed within the EU co-funded, Sixth Framework Program SAFESPOT Research Project, leading to outline the Organizational Architecture of a Road Safety Cooperative System. The purpose was toverify the possibility to apply the general guidelines provided by the Italian ITS reference architecture (ARTIST) to such systems, thus encompassing the challenges introduced by the involvement of a large number of actors from both vehicle and infrastructure environments. The study produced a possible way to supply the SAFESPOT Safety Margin Assistant, by identifying and exploring the roles, responsibilities and means needed for deployment.
