Particles – a problem in enclosed railway environments
From a climate perspective, rail transport in Sweden is sustainable. However, rail traffic can give rise to levels of particles that are harmful to human health. Thanks to various research projects over recent years, VTI has been able to acquire the right knowledge to help address these...

Knowledge in the fight against microplastics from road traffic
The Swedish Government has commissioned VTI to develop and disseminate knowledge regarding the emission of microplastics from road traffic. Government commission regarding emission of microplastics It began with the Swedish Environmental Protection Agency being commissioned by the Swedish...

How can high levels of particles in tunnels be reduced?
A new study from the National Road and Transport Research Institute (VTI) demonstrates that older types of trains produce more particulate emissions in railroad tunnels than do newer ones. Dust binding, improved paving, and reduced studded tyre use could reduce coarse particle levels in road...

Bringing Together Nordic Expertise in Cooperation on Road Dust
Road dust can be cleaned up or bound to the road surface, but more knowledge is needed to determine which approach is more effective. Project Nordust is consequently starting as a Nordic cooperative initiative in which researchers from Sweden, Iceland, Finland, and Norway will work together to...

Major Test: What to Think About When Choosing Winter Tyres
A major debate is underway as to which winter tyres are best, studded or non-studded. But there is more to making a decision as a consumer than just that question. On ice and snow, non-studded tyres made for Nordic conditions differ greatly from those produced for Central European conditions....
