A GIS tool for the emergency management of terrorist actions in the transport of hazardous substances

The management of the terrorism risk is very complex, it requires a systematic and structured methodology that permits an exhaustive analysis of the possible modes of attack and the definition of the vulnerability for the system concerned. This work shows the application to a case study of an effective approach that allows the estimation of the possible damage due to a terrorist action during the transport of dangerous materials and gives some fundamental elements for the management of the emergency. For the correct management of the emergencies the knowledge of the time evolution of some events is an essential element. Thus the study of the evolution of accidental events is the main objective of this paper.
