Norway's urban toll rings: Evolving towards congestion charging?

The role of various types of road user tolls has been an important part of Norwegian transport development for a number of years. There are now around 50 such projects in operation around the country. This paper examines the urban toll ring projects and presents results from new research into the schemes in Norway's three largest cities: Oslo, Bergen and Trondheim. The research indicates that key decisions are being debated as to whether the schemes will continue as toll rings, be stopped completely or transformed into more of a demand management style policy. Interviews with road and local authorities have shown that the feelings are mixed and that the decision will depend on various transport, social, organisational and political factors.This paper reviews the cases of Bergen, Oslo and Trondheim and documents the latest developments in each scheme. The theory behind the application of the toll rings is explored through the case studies. Despite all the projects being implemented by similar networks, each scheme developed its own individual characteristics. These are laid alongside the economic and transport benefits with which they have been associated. The Strategic Policy Niche Management framework is used to analyse various aspects of the toll projects and identify key lessons. The effect these might have on future UK projects is also discussed.
