Abstract [sv]

Particles from wear and resuspension in the road environment are difficult to

handle in emission modelling for many reasons. Primary wear emissions are

affected by a large number of factors related to material properties, traffic

characteristics and temporal and spatial variations in the composition of the

vehicle fleet. Estimations made from measurements in ambient air need source

apportionment studies, while laboratory tests are made on pinpoint samples

taken under non-realistic conditions. Resuspension depends, apart from the

addition of primary wear particles, also on the addition of particles from

exhaust and the environment. Road surface characteristics and meteorology are

important factors affecting the resuspension process. This report summarises

how some different models handle wear- and resuspension particles and

provides an overview of factors affecting the emission of these particles as

well as an overview of relevant emission factors. The models considered are

the American AP-42, the Swedish Dispersion and the Norwegian VLuft. The

report concludes that it is important that data used for particle emissions

from tyres and brakes are as up-to-date as possible, since the composition

varies over time. Relatively good data are available and probably

generalizable. The situation for pavement wear and resuspension is more

complex. These particle sources depend on a large number of factors and are

difficult to separate from each other. Model development should therefore

focus on pavement wear and resuspension processes. For Swedish conditions the

Dispersion model (SMHI), which has great development potential through e.g.

coupling to current maintenance models, is a suitable starting point.
