Road safety evaluation using GIs for accident analysis M. G. Augeri, S. Cafiso & G. La Cava Department of Civil and Environmental Engineering - University of Catania, Italy Abstract It is a very complex task to carry out safety analysis on an existing road network since it requires a detailed knowledge of all those factors that determine the dangerousness of the infrastructure. In order to obtain good results, it is necessary to have complete and reliable information related to accidents, inffastructure features and traffic conditions. It could be complex to manage simultaneously such different information, above all when it is necessary to carry out analysis on wide road networks. In such cases the organization of the information in databases is fundamental, their architecture must be planned opportunely also in consideration of the georeferencing requirement of some data. For this reason the use of Geographical Information Systems (G.I.S.), which allow the integration of alphanumeric inform
