Short summary
A methodology is proposed for the quantitative risk assessment of roadways subjected to rockfalls, retaining wall failures, and slow moving landslides. It includes the calculation of the probability of occurrence of each hazard with a given level, based on an extensive collection of field data, and its association with the consequences. The latter was assessed considering the road damage repair cost for each level in terms of a fixed unit cost.
