How can high levels of particles in tunnels be reduced?

Traffic jam in a road tunnel.
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...
