A New Susceptibility Index for Rockfall Risk Assessment on Road Networks
Abstract
Rockfall susceptibility evaluation of slopes overhanging roads is one of the key elements in road network risk analysis. A new Rockfall Susceptibility Index (Ro.S.I.) was developed for the Autonomous Region of Aosta Valley road network to be used as a part of the ROckfall risk MAnagement (RO.MA.) method. This index takes into account several parameters and has been specifically designed for mountainous areas; it allows a fast analysis at regional scale and can be a useful tool for road managers and other public administrators. This paper illustrates the necessity of this new index and describes the considered parameters as well as the reasons of their selection.
