Initiated January 2007, final report published May 2013.
The road network is influenced by climate conditions. The Norwegian climate in the future will bring higher precipitation – more frequent and more intense rainfall, milder winters, warmer summers, an increase in wind speed and storm frequency. This will affect the road network in several ways. Higher groundwater levels will yield higher probability of floods and erosion. More rain will give a higher risk of slides, occurring at new locations. We may see more of “wet slide types”, such as slush avalanches, debris slides and mud flows. Our premise for the choice of structural solutions and dimensioning of physical protection may be incorrect for the climate conditions and existing slide protection may not be sufficient. Areas exposed to stable winter conditions may experience higher exposure to freezing and thawing. One should also count on reduced accessibility and regularity. All this requires improved emergency plans.
The main objectives of the programme have been to evaluate the effect of climate change on the road network and recommend adaptation measures concerning design, construction, operation and maintenance of the road network. The aim is to maintain both safety and accessibility in a changed climate.
“Climate and Transport” covered the following topics:
- Climate change projections and their impact on design values
- Data: collection, processing and storage
- Flood and erosion protection
- Landslides and avalanches
- Bearing capacity of roads
- Consequences for winter operation
- Susceptibility and emergency plans

Programme transport policy context
The programme has been carried out in close cooperation with the Norwegian National Rail Administration, and with the help of a large number of cooperating partners (also members of the programme board):
Norwegian Meteorological Institute (met.no), Norwegian Water Resources and Energy Directorate (NVE), Norwegian Geotechnical Institute (NGI), Norwegian Geological Survey (NGU), Norwegian University of Science and Technology (NTNU), Centre for International Climate and Environmental Research (CICERO), Directorate for Civil Protection and Emergency Planning (DSB), and Norwegian Institute for Agricultural and Environmental Research (Bioforsk).
The aims of the programme were mainly formulated based on the need of NPRA. However, the results are relevant for other types of infrastructure – for the cooperation partners in the programme and also for Norwegian municipalities.
