Background and Objective: Noise pollution is one of the major environmental problems in cities which has been a growing concern in the last few years. One of the important factor in urban construction designs is noise prevention. According to a study in 2020_2021 in Ahwaz, a suggested is presented for traffic noise compatible to conditions in Ahwaz. Research Method: Data was colleted to design a model from totally 113 measuring stations, 4 weekdays and 2 intervals an rush hours, yielding to a total number of 1344 traffic noise measurements (Leq) and the influencial factors from traffic load, speed of vehicles, environmental and dimensional factors of roads. In the next step, all field data was put to Excel and SPSS, two soft wares for process. Then based on desired overall structure, using analytical and experimental modeling strategies, several Regression multi- variables were tested on data in order to design a model. Results Au recordings collected from 112 measuring stations inchcded 28224 records, a number which is considered a strength point for the present study. The model designed for Ahwaz consists of q inputs with high clarification coefficient (R2=0.92) and correlation coefficient (R= 0.95). The number of inputs allows the model to record important features of traffic to yield more accurate estimations. Conclusion Due to precision and minutness of designing as well as the the number of inputs, the model can be a suitable one to define half – hair equal level for traffic noise and estimation of noise pollution in Ahwaz. The model can be developed by defining variables such as wind speed and gradient, estimation of absorption and reflection by construction materials estimation of absorption by plant species, etc. Keywords: noise, pollution, statistical modeling, traffic, Ahwaz.
