    Abstract: In mountain areas, transport infrastructures (roads, railways) are exposed to natural hazards such as avalanches, torrent floods and rockfalls. Road networks are known to be essential for economic, safety, social, environmental and safety reasons: they can therefore be considered as critical networks. Effects of natural phenomena on exposed roads can affect either users, road infrastructures or the linking function itself with indirect remote consequences. This paper describes a methodology based on structural properties analysis to assess the indirect vulnerability of road networks. Attractiveness factors (population flows, economic activities, access to rescue, health facilities . . . ) are used to identify the importance of road sections. Physical features (slope, width . . . ) and snow avalanches exposure, considering variable quality information, are used as constraints. The software GeoGraphLab (GGL) provides structural indicators which inform decision-maker about their networks criticality and resilience is used in the context of natural hazards.
