Abstract [sv]

In 2004, the Swedish Road Administration and the Swedish Association of Local Authorities published a handbook, VGU, on the design of roads and streets, in which one of the sections deals with road lighting. The main thought in the VGU is to reallocate means for road lighting from roads where the benefit for traffic safety is low, to roads where it is high. Consequently, good road lighting is primarily recommended on roads and streets where unprotected road-users, such as cyclists and pedestrians, pass. The aim of this project was to analyse the effect of reduced or turned off road lighting on motorways, considering road-user behaviour and attitudes. The intention was to use two existing motorway stretches for the trial, both with a large part of commuter traffic. On one road stretch, the existing road lighting should be reduced by half, while it should be completely turned off at the other. Interviews with commuters should be carried out after the lighting reduction, and speed measurements should be made before and after the reduction. Because of the strong negative reaction from one person living close to the road stretch where the road lighting was completely turned off and that this person contacted media, it was necessary to turn on the road lighting again. As a result of this, no attitude study could be accomplished, and no measurements of speed after the reduction on this road stretch were possible. Accordingly, it was only possible to make speed measurements on the motorway stretch where the road lighting had been reduced by 50 per cent.
