Noise pollution control / European legislation



Autostrade per l’Italia and its subsidiaries are carrying out a major investment plan to develop and modernize the highway network.

European legislation


Con il Legislative Decree no. 194 of 19 August 2005 (implementation of European directive 2002/49/CE of the European Parliament and of the Council of 25 June 2002 ), defines a common approach to avoid, prevent or reduce, on a prioritised basis, the harmful effects of exposure to environmental noise.
The approach is based on determination of the noise through noise mapping by methods of assessment common to all Member States, on informing the public and on the implementing action plans. In years to come, this directive will provide the basis for developing Community measures relating to the major sources of noise.

The directive also requires that information to the public be provided by means of "maps", which represent both the current state of the environment (Noise Mapping) and the expected state of the environment following any mitigating actions (Action Plans) and, finally, the efficacy of the envisaged improvement actions.

 

Autostrade per l'Italia interventions
In accordance with the five-year deadlines indicated by European Directive 2002/49/EC and with the national implementation thereof, Autostrade per l'Italia has drawn up five-year updates in respect of:

  • "Noise Mapping" representing noise levels according to specific indicators that are useful for assessing the exposure generated by a highway source;  
  • "Action Plants" which aim to manage noise pollution issues and the effects thereof, by fully incorporating the Noise Abatement Plan; 

 

On 30.06.2012, Autostrade per l'Italia updated the noise map for the entire network under concession, in accordance with Ministry of the Environment prescriptions as set out in the following document: "Preparation and delivery of digital noise mapping documentation on noise mapping and strategic noise maps (Legislative Decree 194/2005) - Technical Specifications Version 2.0 May 2012 ".

Autostrade per l'Italia published the updated Action Plans on its website on 20 April 2013, so that the general public could consult them and submit their comments, opinions and observations in writing within 45 days of the date of publication. 
Autostrade per l'Italia took these comments into account when drawing up the definitive Action Plans, which were published on this website and transmitted to the Authorities on 18 July 2013.

In line with the recommendations of international standard ISO 1996-2, the following colours have been used to represent noise curves.

 

 Noise Level [dB(A)]  Color  
50 Yellow  
55 Ochre  
60 Orange  
65 Vermilion  
70 Carmine  
75 Violet  

 

"Noise mapping" and "action plan" results are not directly comparable with "locating critical area" and "noise containment and abatement plan" results: indeed, European legislation has introduced new noise descriptors (Lden parameter) for assessing noise and different guidelines on how to represent the noise levels were provided (fixed height of 4 meters from the ground instead of at the most critical point, and different calculation methods, namely the French NMPB-Routes-96 model).

For more information on the calculation model used and in line with the requirements of art. 3, paragraph 5, and annex 4 point 6.e of Legislative Decree 194 of 19/08/2005, reference should be made to the Technical Report on the Noise Mapping study and to the Descriptive Report annexed to the Action Plans. 

These documents were produced in accordance with Ministerial guidelines:
"Definition of the minimum content of reports relating to the methodology for determining noise maps and descriptive values of the areas subject to the noise levels" "Guidelines for drawing up the descriptive reports annexed to the action plans, for the purposes of handling noise pollution and the effects thereof".
