Abstract
Road infrastructure safety is a key issue in urban planning for numerous agencies, authorities, central and local administrations, road operators and contractors, in addition to researchers and technology experts. The present study describes a theoretical framework and examines coordination models highlighting how the integration between agencies can be developed with a supporting methodology. By means of alert maps derived from the elaboration of DInSAR (differential interferometry synthetic aperture radar) data, the study defines the actors involved, the alert level for each road infrastructure and the rationale for centralized or flexible coordination models. The potential applications of the approach are tested on a case study in Italy, in an area with about 1600 km of roads in Rome. The study aims to promote synergy between the various agencies for more sustainable infrastructure safety planning and governance.

A change in perspective is currently taking place in relation to road infrastructure safety management
In order to deal with these limitations, the present study proposes the use of satellite observation techniques with a view to defining alert maps in GIS
The present study outlined an integrated approach to road infrastructure safety considering multiple infrastructures affected by shared safety issues
Summary
A change in perspective is currently taking place in relation to road infrastructure safety management. It considers a range of infrastructures and the various actors entrusted with their management such as the public authorities, central and local administrations, road agencies and operators It examines the consequences of safety issues, ranging from the domino effects among interrelated infrastructures to the factors undermining the integrity of the surrounding territory. Alert maps can indicate the agents to involve, since they are responsible for the management of the specific infrastructure, and, according to the alert level, have roles in decision-making (see Section 4) This information can be incorporated into the proposed theoretical framework aimed at explaining how to coordinate the actors involved. The present study is founded on certain principles that are widely applied in emergency management to support efficient models of integration between the actors involved dealing with a general emergency originating from critical infrastructure safety issues.
