    Abstract: In Norway, approximately 2000 landslides and avalanches affect the road network every year. Projected climate changes will give a milder and wetter climate in Norway with more extreme weather events. These changes are expected to affect the avalanche and landslide frequency. In order to adapt to expected climate changes, the Norwegian Public Roads Administration initiated a 4- year R&D programme in 2007 called “Climate and Transport”. One of the main topics in the programme is landslides and avalanches, and how climate changes are expected to change the probability for and frequency of these events. Within the subject of avalanche and landslide risk on the road network, the level of acceptable risk has not been established, and in an attempt to describe the avalanche and landslide risk more thoroughly, a risk model concerning these conditions has been developed. The model is still in a premature state, and testing on certain road sections will be done in near future.
