Fugitive dust emissions due to car traffic on streets in Vienna

Fugitive dust emissions resulting from street car traffic in the city of Vienna were determined over a period of 17 months. The emission factor over the measuring period was calculated by measuring the silt content (sL-value) of different selected streets and using the available traffic count data. It is shown, that strewing crushed stone on streets in winter has a major influence on fugitive dust emission. A comparison of these emission factors with ambient air measuring data over the same measuring period shows parallel curves, which shows that resuspension of the dust deposited on streets affects air quality in the city of Vienna.
