Transport

In this research field, we study changes in travel, public transport, freight transport and the importance of transport investment for regional development.

Over the course of 2016, among other areas, we conducted research in:
 
  • Evaluation of a Pilot Project with the operation of electric buses

IRIS evaluated the introduction of two electric buses on scheduled routes on Nord Jæren, over a period of 18 months. The experiment showed that it is possible to achieve stable operation with electric buses, but a larger scale introduction requires an efficient service/maintenance network. If all diesel buses operating in intra-county routes are replaced with electric buses, CO2 emissions from road traffic in Norway would be reduced by 3.5 percent.
 
  • Choice of concept of connections between eastern and western Norway

After doubts about the Norwegian Public Roads Administration recommendations concerning the choice of concepts in connections between eastern and western Norway were raised, IRIS has reviewed the investigative work that was carried out in recent years. We found no scientific methodological approaches that indicate that the recommended concept with the E134 as the main motorway between Bergen and the eastern region of Norway should be changed.
