Road traffic noise, commonly considered as the most directly unpleasant consequence of road transportation, has been found to have detrimental effects on human well-being when individuals are exposed to prolonged periods of excessive noise levels, particularly in industrial settings. The primary aim of this research is to evaluate and estimate road traffic noise in Egypt. The study encompasses comprehensive road traffic noise surveys conducted at three specific locations within Cairo, along with peak noise emission surveys conducted for various vehicle types. The subsequent analysis reveals that existing models developed for other countries are not suitable for accurately predicting road traffic noise in Egypt. However, a new model specifically tailored for Cairo exhibits a strong correlation with real-world data. Additionally, this model aids in identifying the critical factors influencing traffic noise levels by establishing threshold conditions. The findings of the noise assessment indicate that both community noise levels and peak noise emissions in Egypt surpass acceptable standard levels, emphasizing the urgent need for mitigation measures.
