  • Mitigation measures to minimise traffic–generated noise pollution in Metropolitan Kuwait

    Forty representative roadway locations were randomly selected for monitoring traffic flow and noise levels. At local streets, equivalent noise level (Leq) ranged between 56 to 71; at collector streets traffic areas 70 to 83; at arterial roadway 75 to 86 and at freeway roadway areas 75 to 88 dBA during day and night time respectively. Consequently, the level of noise pollution from traffic even at ...
