Functional Analysis of the Urban Road Network in Seismic Emergencies: a GIS Application on Catania City

Road infrastructure, as it is easily know because of the dramatic seismic experiences that have recently happened in California (Loma Prieta, 1989; Northridge, 1994) and in Japan (Kobe, 1995), assume a central role in the management of the emergency both in the phases that follow the disaster, in order to guarantee a timely reaching of the affected areas with first aid means, and in the “long term” for an optimal planning of repair and rebuild operations. Only after these disasters, has a consolidated knowledge about the problem been acquired; indeed, a large number of studies on the evaluation of seismic risk have begun, also taking into account the fundamental role of the road network, mainly according to the problems of direct and indirect seismic exposure. Nevertheless, the majority of these studies have been developed on rural areas, often neglecting the similar problems concerning the management of the emergency inside affected urban centers. In order to provide an operative methodology to analyze and verify the reliability of urban road networks (Lifelines), this paper address these problems in order to guarantee safe routes for timely access to the aid coming from outside. The proposed methodology finds as a natural applicative completion the advanced geographic information system (GIS) software functionalities, which represent not only a powerful instrument for filing and positioning the various data to be handled, but also advanced analysis and querying systems to support decisions (DDS). The entire procedure has been applied to a district of Catania city, obtaining important results which validate the proposed methodology.
