Noise measurements can be strongly affected by weather , P lacement <br />of traffic control devices, design and condition of the roadway= <br />and topography. A comparison of the noise model predictions and <br />the noise measurements can provide additional information about <br />the affect of localized conditions on traffic noise. <br />-------------------------_------------------------------------------------- <br />1.
