Effect evaluation of standardization on data base of traffic noise prediction model of Ahwaz city

Background and Objective:Noise pollution is one of the major environmental problems in cities. One of the most important sources of noise pollution is transportation.present study was implemented in ۲۰۱۱ with an overall goal of Effect evaluation of standardization on data base of traffic noise prediction model of Ahwaz city .Research Method:For this study ,data was colleted from totally ۱۱۲measuring stations, ۴ weekdays and ۳ intervals as rush hours, yielding to a total number of ۱۳۴۴ 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 Regression multi- variables were tested on data in order to present some stasistical models.Results The findings of this study showed that average of equivalent Sound pressure level in all stations is equal to ۷۲/۶۲ ± ۲/۵۳ dBA. Also, the standardization had a good role on scattered data.ConclusionAccording to the result of this study, clarification coefficient can be effected by standardization.
