Zusammenfassung

Tire abrasion (Tire Wear Particles, TWP) has been identified as a major source of microplastic emissions. In order to understand the pathway of TWP in the environmental compartments the authors aimed to develop a model for the spatial distribution of TWP along the roads, which can be implemented in planning and decision tools allowing public authorities to identify hotspots. Thus, they combined a probabilistic and GIS (Geo Information System) model in order to calculate and map the TWP distribution for Germany. Basing on a specifically developed GIS data set for all federal states the distribution of the entire mass over all roads were modelled by the means of statistical data (traffic distribution, stress intensity, weather, etc.). Within the present paper the results are discussed as example of Berlin.
