International are in-troducing new interactive graphical interface enabling direct as-sessments of impacts of urban road traffic emissions with respect to population health. Different traffic control scenarios can be tested by modifying traffic volumes and speeds on se-lected roads or in entire neighbourhoods. Consequences of such changes in terms of air pollution and health impacts can be then reviewed and evaluated in mapping and tabular formats. The interface can be installed as a stand alone application on a PC or hosted on a dedicated web site.
