TRAFFIC NOISE MEASUREMENTS ON URBAN MAIN ROADS WITH GRADIENTS

Measurements of road traffic noise were made at 18 locations on single-carriageway hilly main roads, subjected to speed limits, in the greater London area. The observation sites were 10 M from the kerbside and in positions where the flow of vehicles was relatively steady. Variations of L10, L50 and l90 with rates of flow of heavy and light vehicles, and also with gradients, were determined. The changes of the sound levels with vehicle flow followed a predicted pattern. Because of the relatively high degree of scatter obtained in determining mean values of L10, L50 and L90 under given conditions, for a particular gradient, no definite relation could be established between sound levels and gradient. /Author/TRRL/
