The Impact

Contraction joints in rigid (concrete) pavements are required to permit expansion of each monolithic section of roadway. At higher speeds, the major source of highway noise is attributed to vehicle tire/roadway interaction. Current concerns about limiting the impact of highway traffic noise, has forced transportation agencies to consider strategies to control noise generated by tire/roadway interaction. Within this work the difference in noise generated by 1/4 versus 3/8-inch joint widths is conducted. The study focuses on passenger vehicles including a sedan and a light duty van/truck. Both vehicle in-cabin and roadside noise levels are measured for vehicle speeds of 50, 60, and 70 miles per hour. For the sedan, the minimum and maximum observed in-cabin differences were determined to be 1.08 and 1.82 dB(A), respectively. Minimum and maximum observed roadside differences are 1.19 and 2.58 dB(A), respectively. Van tests resulted in minimum and maximum observed in-cabin differences of 0.60 and 1.09 dB(A) and minimum and maximum observed roadside differences of 1.05 and 3.18 dB(A), respectively. This paper contains details of reference standards, test methods, and the results obtained.

The Impact

To study the traffic noise on an Indian urban highway, traffic noise levels (Leq, Lpeak, Lmax and Lmin), traffic volume, speed and honking incidents were measured in peak traffic hours in the morning and evening. An attempt has been made to characterize the traffic noise including the impact of honking. Honking of horn was positively correlated with Leq and negatively correlated with traffic speed. In case of traffic volume and road width, no significant correlation was established with Leq. Based on the observed honking and Leq in each time interval, statistical analysis was performed for assessing the impact of honking on traffic noise and its estimation through trend analysis. Further, quantification of honking noise was carried out considering frequency analysis of audio spectrum of traffic noise. Both the analyzes confirm the honking contributed an additional noise of 1–4[Formula: see text]dB(A) over and above the traffic monitoring noise. The study suggests that honking noise must be included as a factor while monitoring traffic noise in some places where honking is common practice. This study will help in characterizing the traffic noise and the impact of honking for further abatement studies.

Highway Noise

A Highway Prediction Model (HPM) using the ray acoustics modeling approach is developed in this research. The HPM model can be used to quantitatively predict the environmental noise levels on highways of different pavements. Comparison between the measured noise levels using the SPB method and predicted noise levels with the model developed shows that the prediction model established is reliable for estimating highway noise in Canada.
