BAB II / Verification of the accuracy of calculated emissions of vehicle traffic

Verification of the accuracy of calculated emissions of vehicle traffic

Project Description


Verification of the Accuracy of Calculated Emissions of Vehicle Traffic

Reduction of the pollution of the atmosphere by emissions is a political objective. To demonstrate the success of reduction strategies, emissions from individual sources have to be measured.

Vehicles emit among others NO, CO, hydrocarbons, and particles. These emissions result in high ozone concentrations in the summer. Smallest particles, such as diesel soot, are suspected to be harmful to human health. In addition, they affect the climate and contribute to the greenhouse effect.

Based on model calculations, prognoses are made with regard to the future pollution of the atmosphere. As the model results serve as a basis of decisions in environmental policy, accuracy of the calculated emissions is gaining importance. As far as emissions by road traffic are concerned, the quality of statistico-numerical emission calculation models is currently being verified by the BAB II (federal motorway) measurement program.
