150. Table 26.24 indicates one road link (link no. 6 Paper Mill Lane) is likely to experience an increase in traffic flows greater than 25%; therefore a noise impact prediction calculation was required for a residential dwelling adjacent to this road.
151. The predicted increase in LA10,18h noise level at 80 Paper Mill Lane was calculated using SoundPLAN, which incorporates the CRTN assessment methodology. Table 26.25 shows the predicted road traffic noise levels for the baseline and baseline plus Scenario 2, and the relative predicated change in road traffic noise level.
