Traffic Noise Essay

Abstract— In Iraq, statistic of vehicle ownership kept increasing every year. Hence, there is probability of traffic noise levels to exceed the limitation by Iraqi Department of Environment. Generally, intersections produce more traffic noise than free flow. This study will measure level of noise at intersection around Al Muthanna, Al Saad and Al Askan. Level of noise is expected to be influenced by traffic performances. Therefore, we can predict the improvement to be done. Level of traffic noise was measured by using a sound level meter (models 1800 and 2900) from Quest Technologies. Reading of noise was recorded in average between 15-min intervals, Leq at moving approach and stopping approach. But, measurement was done simultaneously at both approaches during 2 hours peak periods. Two points of measurement have been done for every approach with the distance of 15 meters. At the same time, traffic flows were recorded by using CCTV (VZOR). The data were analyzed manually to get the traffic composition and total flow. Traffic noise at moving

I. INTRODUCTION
Rapid industrialization and overcrowding characteristic of large cities will results into noise pollution. It is a significant environmental problem in many urban areas. This problem has not been properly recognized but the fact that it is steadily growing in developing countries[2].
In real life, we are always surrounded by sound. Some of it is pleasant but some is disturbing such as noise at intersection or from highway. In some places, this can really be a problem. Overall purpose of this study is to measure the level of traffic noise distribution at unsignalised intersections. Therefore, it needs to measure any correlation between the traffic performances with the level of traffic noise. Hence, suggestion of any necessary improvement for the traffic facilities related to unsignalised
