“…A significant difference of 7 dB (A) to 10 dB (A) was observed with change in the noise characteristics of pavement surface types and recommended the consideration of the respective surface types prior to the selection of highway. Moreover, each vehicle class was generating different noise levels at the same vehicle speeds (Kamineni and Chowdary, 2016). This shows the necessity of considering the proportion of the vehicles in order to develop the traffic noise prediction models for any road.…”

Compared to homogeneous traffic flow, traffic speed variation is drastic with the involvement of heterogeneity. With an intent of studying the negative upshot of fluctuating speeds of heterogeneous traffic on the environment, the current paper is the outcome of the research done on various highways located in the states of Andhra Pradesh and Telangana in India, with an objective of developing a comprehensive noise prediction model by taking into account the traffic and roadway factors. Quantified noise levels [Leq (dBA) and L10 (dBA)] revealed that for the traffic speed variation of 10 to 95 kmph, the traffic noise levels were significantly affected by the variations in the proportion of the vehicle. On a specific note, the proposed model can be effectively used for the highway traffic noise prediction especially for the heterogeneous traffic, as the difference between the measured and predicted noise levels are within 1 to 10 dB (A).

Vehicle speeds frequently fluctuate due to the prevailing heterogeneous traffic conditions on Indian roads. Accordingly, traffic noise levels are affected by different noise sources that depend on various vehicular and roadway characteristics. In order to simulate the actual vehicle noise generation at the possible speeds on Indian roads, an integrated method has been developed in this study to quantify the engine and tire–road noise levels. The governing parameters considered for the pass-by noise quantification include vehicle speed, type of pavement and gear shift/gear transmission. The measured A-weighted noise levels [LAmax (dB)] revealed that tire–road noise levels increased with the rise in vehicle speeds irrespective of the vehicle type and type of the pavement. Further, the tire–road noise levels quantified through the new methodology closely matched the noise levels measured by the standard coast-by method. The cross-over speeds for engine propulsion noise and tire–road interaction noise occur at much lower speeds on the cement concrete pavements compared to the asphalt pavements. On a decisive note, the perspective of measuring the roadside noise levels coupled with an engine propulsion noise measurement as reported in this study is first of its kind and can be used for noise measurements on critical urban roads by priming with the conventional pass-by methods.
