Identification of the Critical Components in a Transportation Network: A Case Study

摘要

In actual transportation infrastructure networks, relatively new and old, or even ancient, constructions coexist together. Satellite images with high resolution (i.e.. of the Ikonos class with 1m of resolution) can be the basis for the Geographical Information System (GIS); repeated image acquisition (twice per year, for instance) allows one a real time update of the global information. The satellite image will support an integrated database, including: ⅰ) structural component design and maintenance status; ⅱ) earth work in terms of characteristics and actual maintenance; ⅲ) surrounding basins and relevant hydro-geological data base; ⅳ) seismic (if any) catalogue and any other source of hazard for the system under investigation. The infrastructure system connecting Italy to France is an ideal case-study, due to its functional relevance and critical aspects of local environmental conditions.
