First conclusions about the END implementation: EGRA Spanish road strategic noise mapping experience

The Direccion General de Carreteras of the Spanish Ministry of Transport started one year ago the process of Strategic Noise Mapping of Spanish Major Roads (EGRA). The methodology applied for Noise Mapping and the quality control procedure defined to monitor the work done by different contractors were already presented in EURONOISE 2006 by the same authors. The whole National road network to be noise mapped for the first END round was divided into 20 contracts. At this moment 5 of those studies are finished and the other 15 studies are under development during spring 2007. So, the whole network is already on the process. The present paper contains -First conclusions about the robustness and coherence of the methodology adopted; - Some comments to the second version of the Good Practice Guide; - Suggestion about used indicators and its validity to set priorities for Action Planning; and - View to the first results obtained in terms of people, land and buildings exposure to noise.
