The variability of road traffic noise and implications for compliance with the noise conditions of roading designations

摘要

Many road designations have conditions with respect to noise, requiring that when the road is completed measurements will be undertaken to prove that the performance standards of those conditions have been fulfilled. However, all measurements are subject to variability, and the designation conditions do not address either the expected nature of this variability or how it should be accounted for in establishing compliance with the conditions.
