Abstract	Vehicular movement on roads generates noise noise-intensive environment posing potential risks. Environmental impacts due to traffic movements have been avidly studied. Few studies have dealt with noise variability. This paper presents an analysis of results for locations along grade separators for environmental noise measurements. The locations were grouped with similar attributes, and the noise impact of traffic was observed. The A-weighted sound levels, ninety, fifty, and ten percent exceedance levels (L90),(L50),(L10), and derived noise descriptors: Noise climate (NC ), Traffic Noise Index (TNI), and Noise pollution Levels (LNP) were higher at all locations. ANOVA single-factor and the Tukey criterion applied identified high-speed links generating noise-intensive environments. Analysis indicated a high correlation between vehicular speeds and noise. Also, Higher noise levels and minimal noise variability in free-flow conditions indicate more exposure. Results are significant for understanding implications for favouring measures for faster modes and aid in assessing trade-offs between sustainable and economically biased solutions and decisions.
