Tillståndsmätning av vägmarkeringars funktion år 2009 i SMN, SST och SSÖ


Starting in 2000, condition assessment of road markings have been carried out in Sweden. As previously, the purpose of the study has been to answer the questions: - To which degree is the performance in the Swedish regulations fulfilled? - Is there any difference in road marking quality within the same region, i.e. between the counties? - How has the performance fluctuated over time?

The retroreflectivity and macro texture of dry road markings have been measured using the RMT version 2 in 2009. The retroreflectivity of wet road markings and the skid resistance have been estimated from the dry performance and the macro texture.



Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...
