Abstract
Each year millions of tons of Dangerous Goods are transported between France and Italy using especially road and rail transportation systems. These DGT cross the territories that gather dense urbanized places, critical infrastructures (highways, tunnels, bridges etc.) and organizations (hospitals, police and firemen centres, rail stations etc.), and protected areas (national, regional and departmental natural reserves and parks). According to the definitions of vulnerability and resilience, the authors propose a spatial model based on two indices in order to characterize the level of vulnerability and resilience of the territory induced by the DGT. Those two indices are implemented into a Geographical Information System (GIS) in order to define a Spatial Decision Support System (SDSS) dedicated to the decision-makers (infrastructures managers, public authorities and transport companies). As a conclusion, the authors discuss the levels of vulnerability and resilience of the territory according to the different kind of transportation systems, i.e. rail and road in order to underline recommendations for DGT planning.
