Abstract
The Italian legislation prescribes that the managing authorities of transportation infrastructures have to preparea noise control and abatement plan, using established procedures and indexes defined both at national and regional level.The aim of the paper is to compare the standard procedure given by Umbria Region with three innovative methodologiesproposed by the authors to increase the adequacy and the quality of roads noise planning activity. Both standard andinnovative approaches require the creation of a ranking of priority to define where noise abatement actions are mostnecessary. The proposed methodologies introduce at various levels a more detailed phase of noise mapping, by usingfaçade noise map instead of grid noise map, and define new rankings of priority based on improved location of calculationpoints. More accurate and realistic noise plans allow to optimize the budget allocated for acoustic rehabilitation and tomitigate the most critical situations. The innovative procedures can be easily transferred at European level for therealization of Noise Action Plans requested by the Environmental Noise Directive 2002/49/EC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
