Strategic noise maps expect to assess the impact of the predominant noise sources in the current society, to define action plans in a later phase to mitigate the affected areas. The study sphere for which these Strategic Noise Maps have been developed - noise level maps, noise exposure maps and noise impact maps – correspond to 12 roads of Valencia with more than 6 millon vehicles per year, to the A-3 y A-7 expressways, which are longer road axis, the V-11 and N-220, which are urban through roads, to the V-30, which is the Valencia bypass, etc. Criteria adopted for assessing the affected population, the tools used and the solutions proposed to obtain reliable and representative information have been developed taking into consideration the directions of the General Directorate of Roads, the good practice guide of the working group WGAEN and the experience in acoustics of our experts. Maps at scale 1:25.00 and contour lines every 10m are developed in the A phase. Later on, the areas which will be studied in detail in the phase B are selected at scale 1:5.000, and contour lines every 5m.
• Plan of the study area. • Example of map developed during Phase A. • Study three-dimensional model. • Examples of area analyzed in detail.
