ABSTRACT
Risk and exposure of the road corridors of Matera Province (Basilicata Region, Southern Italy) to landslide phenomena was assessed. The provincial road network (1,320 km length) represents the main connection network among thirty-one urban centers due to the lack of an efficient integrated (road, railway and aerial) transportation system through the whole regional territory. The strategic importance of these roads consists in their uniqueness in connecting every urban center with the socio-economic surrounding context. The exposure was evaluated in terms of amount of traffic, as a function of population of each centers. The vulnerability was assessed in function of the presence of criticalities along roads. The exposure and vulnerability to landslides were combined in order to evaluate and map the risk. The classification of the road sections in terms of risk levels represent a support for decision making and allows to identify the priorities for designing appropriate landslide mitigation plans.
