Abstract

Given the importance of road networks for the development of a country, it has become increasingly important to incorporate risk management into traditional road network management systems. Risk Management Systems (RMS) are used to estimate the potential consequences of natural events and to assess strategies for risk reduction and increase in resilience. This article discusses the development of SIGeR-RV an tool developed in Chile for road networks exposed to multiple natural hazards. The RMS was implemented in a web-based Geographic Information System platform able to display hazard maps, quantify risk levels, prioritize mitigation strategies, and estimate direct and indirect costs and social vulnerability. This first version of SIGeR-RV considers seismic hazard, volcanic lahars, and hydro-meteorological hazards that affect road platforms, bridges, tunnels, and cut-slopes.
