A Correlation Analysis of Noise Level and Traffic Flow: Case of One Way Road in Banjarmasin

Noise on the highway cannot be avoided, given the increasing number of vehicles on the road. Such noise is known to be influenced by several factors, one of which is the distance from the noise source. A collection of exhaust sounds from vehicles in traffic is one such source of noise. This study aims to obtain the effect of traffic on the impact of noise generated on the open area without obstacles based on a predetermined distance of 0 meters, 17.5 meters, and 35 meters. From the result of the analysis, it is obtained that the traffic flow has a strong correlation level as a source of noise at the distance and noise levels show a decreasing level of correlation. At a distance of 0 meters (roadside) obtained correlation level is close to very strong (0.896). At a Distance of 17.5 meters, the correlation rate decreased to 0.823 and at a distance of 35 meters r-value to 0.814. The average noise change due to traffic activity is 0.29 dB per meter from roadside to 17.5 meters, and 0.15 dB per meter from 17.5 meters to 35 meters of the noise source. Thus, it can be concluded that the closer the distance to the traffic or noise source the greater the noise generated and the farther the distance from the traffic the less noise it generates
