This plan covers five years from 2013 to 2018 and lays out the measures that the councils intend to take to manage environmental noise exposure. The plan also contains an assessment of possible noise hotspots throughout the area. This is done by using complex software to make predictions about the noise generated from traffic in different areas. These predictions do not always show the actual sound levels at a given location, but they do show what areas are likely to be most affected by noise from busy roads. The action plan then looks at some ways to try and address exposure to this noise by managing the environmental impact of these transport systems.
