CNOSSOS-EU Guidelines for the competent use of the future common noise assessment methods

1. CNOSSOS-EU Guidelines for the competent use of the future common noise assessment methods • Fabienne- Anfosso- Lédée • Stylianos Kephalopoulos • Associating S. Shilton, M. Paviotti, N. Jones, T. Werst, P. de Vos, D. van Maercke, V. Reina

2. CNOSSOS-EU Guidelines Concept Introduction Background Objectives and scope of the Guidelines How will the Guidelines look like? Proposed structure Examples from the template Some Technical Issues to be Addressed Future Needs

3. Background (1/2) • JRC Workshop March 2009, Ispra: “Target Quality and Input Values Requirements”: • Extensive discussions highlighted need for Guidance. • JRC Workshop September 2009, Brussels: “Selection of common noise assessment methods in EU” • Extensive discussions identified initial scope of Guidance; • Euronoise October 2009, Edinburgh: “Noise Mapping Workshop” • Presentation of recommendations from September JRC workshop and discussion open to experts from outside the working groups; • Lively debate amongst delegates, predominantly centred on the practical application of the proposed methods; • Provided clarity on the required scope of the Guidance.

4. Background (2/2) • JRC Ad-hoc Meeting with Software Developers (CNOSSOS-EU), March 2010, Ispra • first presentation of the concept, scope and outline of the Guidance • discussions and starting point for an outline agreement on the overall form and scope of the Guidance • DG ENV Meeting of the Joint Regulatory Committee Meeting on Noise, June 2010, Brussels • EU MS reiterated the need for Guidance for a competent use of CNOSSOS-EU as an integral part of the common method • EU MS also expressed their views on what the Guidelines should contain.

5. Objectives of the Guidelines The purpose of CNOSSOS-EU is to support the Directives’ requirements on comparability and equivalence, therefore, the Guidance should provide: a framework for a common implementation of the END. extensive practicalguidance to support the users in the application of the proposed CNOSSOS-EU methods Technical chapters of CNOSSOS-EU focus on WHAT the method entails – the “Standard”; Guidance chapters of CNOSSOS-EU focus on HOW the method should be used in practice. The Guidance should support and encourage sharing of data, experience and best practice between stakeholders, support the aims of the INSPIRE Directive.

6. Scope of the Guidelines (1/2) bring together the key aspects of best practice currently set out within an array of documents and reports. WG-AEN, “Good Practice Guide for Strategic Noise Mapping and the Production of Associated Data on Noise Exposure”, Aug. 2007; WG-AEN, “Presenting Noise Mapping Information to the Public”, March 2008; OJEU, Commission Recommendation 2003/613/EC EC, Reporting Mechanism proposed for reporting under the END 2002/49/EC - Handbook (including Data Specifications), Oct. 2007. IMAGINE, WP1 Final report , 2006 DIN 45687 Various national guidance documents … • Guidance of CNOSSOS-EU is to be developed and extendedbeyond the aforementioned available documents.

7. Scope of the Guidelines (2/2) • “Fit for purpose” framework • A comprehensive methodology to support detailed assessments; • Simplified for strategic noise mapping using default inputs and/or other assumptions. • According to EU MS, the Guidelines need to indicate the necessary quality of input data • provide instructions on the evaluation of emission data: • how to import national databases in CNOSSOS-EU • how to introduce new data • indicate the impact of simplifications of input data. • be flexible to accommodate local and regional variations (complex situations such as valley zones)

8. Who are the Guidelines for?

9. Proposed general structure 5 embedded levels of use defined • Level 0: “Overview”:Framework description of the method, aimed at general public and politicians • Level 1: “The assessment process”:Explanations for the environmental offices and managers of the process at MS level • Level 2: “Description”:General explanation of input data requirements and use of the method. Aimed at persons performing the noise mapping calculations • Level 3: “Toolkit”:Exact list of inputs to be used in the calculation. • Level 4: “Details”:Hints of the settings and input values, clarification of specific issues, data format tolls for National databases conversion, tools for introducing new values, use of measurements

10. Items in the assessment process (level 1) • Areas of assessment • Road noise source emission • Railway noise source emission • Industrial noise source emission • Aircraft noise source emission • Sound propagation • GIS and dataset specifications • Noise level calculations • Measurements • Reporting of Results • Public Participation

11. How will the Guidelines look like? An interactive web based tool, hosted by JRC • Staged development according to priorities • Updated information • Possibility to get information at different levels of details • Possibility to send comments directly from the site, to suggest improvements or to share experience

12. Level 0 TEXT TO BE DRAFTED

13. Level 1

14. Level 2

15. Level 3

16. Level 4

19. Development process • Small expert group (9 people) coordinated by JRC, for building the web site and preparing a draft proposal (S. Shilton, M. Paviotti, N. Jones, T. Werst, P. de Vos, D. van Maercke, F. Anfosso, S. Kephalopoulos, V. Reina) • Structure table: list of all items to be fed in the Guidelines at each relevant level • Priorities are assigned for each item • Priority 1: essential, items needed for noise mapping • Priority 2: medium, items can be useful for noise mapping • Priority 3: low, items can be useful for action planning only • Building of web site template according to the item structure table • Drafting of all screens according to priorities • Formal reviewing and finalisation (by the group of experts officially nominated by EU MS and other stakeholders)

20. Some technical issues to be addressed (1/2) • Input Data: • How to capture specific noise related data, such as train emissions, vehicle noise, rail/wheel roughness, road surface info etc; • How to link with national data and take into account specific data • Data specifications for inputs and outputs for CNOSSOS-EU • Management of uncertainty/quality: • in terms of dB uncertainty or no of people uncertainty; • controlling uncertainty as per DIN 45687 standard • GPGv2 Toolkits: • Needs to be updated and expanded to deal with CNOSSOS-EU, what to do when you have or don’t have data;

21. Some technical issues to be addressed (2/2) • Post processing: • Interpolation of grids for “missing” points or contours, presentation of maps, population exposure assessment, reporting to EC , presentation to the public and stakeholders • Use of noise mapping software: • User settings and calculation processing, receptor points for population assessment, grid resolution,…

22. Future Needs • Establish CNOSSOS-EU support working group; • To provide feedback, clarification, support, training and answers to EU MS, software developers and end users; • To manage the test protocols, verification process and accreditation; • To manage and update the CNOSSOS-EU method and Guidelines.
