Det nya hastighetsgränssystemet: regionala beslutsfattares syn, problembilder och erfarenheter efter etapp 2


This study aims to provide a comprehensive description and analysis of the new speed limit system in Sweden on the basis of decision-makers perspective on regional and municipal levels for Stage 2 of the implementation process. The study focuses on the regional perspective and assesses regional impacts of changes in speed limits on national roads outside urban areas. To obtain the data sets needed to describe and analyse decision makers', in different regions of Sweden, views on the new speed limit system, qualitative interviews was selected as the method. The interview responses show that the implementation process in Stage 2 has been developed and improved in comparison with the corresponding process in Stage 1. The better link that many stakeholders called for between changing speed limits and measures in the investment planning has been improved during Stage 2. The Transport Administration has in the proposals for reduced speed limits indicated which deficiencies in road design justifying the lowered speed limit, and what steps need to be taken to remain at the current level. However, many respondents still believe that the Transport Administration does not sufficiently take into account that at the regional level, the issue of speed limits to a great extent is a politically charged issue caused by the assumed relationship between speed, accessibility, travel times and regional development. Regional associations, municipalities, counties, etc. need time to anchor political issues and allow politicians to get the time to familiarize themselves with the changes and take clear political decisions and positions in political assemblies of boards andcommittees on the issue of changing speed limits.
