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

More sustainable urban transport with reduction in car use is one of the main objectives in Norway's National Transport Plan for 2006-2015. Demand forecasts predict that the increase in transport in the future will primarily manifest itself as growth in car use if we do not control the use of cars

This sub-programme focuses on NPRA’s strategy for tunnels and follow up issues described in two reports. These reports were written as a consequence of rockfalls in Norwegian road tunnels and reveal the need for improved tunnel maintenance and geological documentation systems. Major issues, such as

The transport research carried out by NPRA and other Norwegian R&D funds has mainly been carried out on passenger transport. Research on freight transport has so far been insufficient. The growth in freight transport on the roads has been considerable for several decades, but from 1995 there was a

Combined transport as a sustainable alternative to the road transport aims to carry goods in transit primarily on railways and waterways. The extension of combined transport leads to more road safety and less heavy traffic on the road network.

This programme is aimed at the promotion of R&D work successfully concluded and to promote innovation through the implementation of demonstration actions or pilot projects providing innovative solutions.

One objective of Norwegian transport policy is to develop more welfare optimal transport services in urban areas. This research programme shall provide a scientific foundation for organisational or financial measures to meet this target. The programme will provide a basis for developing more

The Institute of Transport Economics has carried out evaluations and assessment programmes for different measures for improving public transport and their effects on the passengers transport sector as a whole. The aim of this programme is to improve the existing analytical tools in order to provide

The general trend within travel behaviour is that the proportion of car trips and the distance travelled per person is increasing. At the same time there has been a modal shift from sea and rail freight over to road freight. In total this leads to more road transport which again has environmental

'Transport and economic development' is a strategic research programme within TOI's wider 'Cost benefit analysis' research area. The main objective of the 'Cost benefit analysis' research area is to develop methods and tools for the appraisal of strategic transport plans. This includes the
