Effects of Low Emission Zones in European cities

Posted on March 5, 2019 by nradmin
Most Low Emission Zones have been implemented because the cities did not comply with the EU Limit Values for local air quality. In a new report, researchers at TOI investigate regulations for and enforcement of European Low Emission Zones (LEZs) and evaluate the effect of LEZs on local air...

How can high levels of particles in tunnels be reduced?

Posted on February 23, 2017 by nradmin
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...

Emission of Inhalable Particles from Studded Tyre Wear of Road Pavements

Posted on August 6, 2015 by nradmin
In the following study, the particle generation from seven studded tyres was tested in the VTI road simulator. The results show that increased number of studs and increased stud force increase the emission of inhalable particles significantly. New restrictions on the number of studs on studded...
