Study of the ADMS-Urban model potentialities as a tool for the air quality assessment and territorial planning

The study carried out consists in the implementation of the ADMS- Urban dispersion model, adopted by the Provincial Offices of ARPA (Emilia Romagna region), for the assessment of air quality within the different emission scenarios due to vehicular traffic in Ravenna. The following different scenarios proposed are three: the “zero” scenario is based on the current vehicles flow that may be found in the town centre streets of Ravenna while the other hypothetical scenarios refer to the traffic hold-ups provided for by the Fourth Air Quality Programme Agreement, drawn up by the Emilia Romagna regions administration offices as to the most polluting vehicles, aimed at reducing the pollutants level into the city atmosphere and especially the PM10 level. The study proposes the methods followed and shows the first results obtained.
