Organizational Analysis to Improve Safety Planning of Road Networks.

The old age of existing road infrastructures has highlighted different issues related to safety management and governance of road systems in many European countries. In fact, safety problems are affecting infrastructure networks generating the need of a sustainable planning of interventions as well as management of traffic flows in a territory. In this context, the different private/public actors have an active role to minimize undesirable economic and social impacts. The present research addresses this issue by means of an organizational analysis based, first, on the identification of all the stakeholders who can define appropriate decisions following specific organizational models. Considering a road network in Rome (Italy), the study proposes the remote sensing by satellites as a useful tool for the stakeholders within a territorial investigation. Indeed, the safety issue of road networks needs complex analyses where all the elements have to be investigated together to achieve a more comprehensive understanding of the organizational issues to improve their governance.
