Studying the factors that affect urban road noise – Case study: El-Tahrir Street, Al-Dokki Cairo, Egypt

Abstract

Expanding road networks to accommodate various activities has increased urban noise pollution, adversely affecting human health and quality of life. Numerous factors, including road characteristics, traffic characteristics, surrounding buildings, and weather conditions. This study aims to monitor and analyse the effect of these factors on the noise level. Cairo is one of the most densely populated cities in the world, which has led to a high level of noise in its different areas. One of the most crowded areas in the city is El-Tahrir Street in Al-Dokki, which was selected as a case study in this research. This area is distinct by a wide range of services and activities, and it experiences high traffic volume, with up to 1,700 vehicles passing through within a 15-minute interval. This significant traffic volume is the primary driver of the elevated noise levels in the area. Traffic and noise level monitoring has been conducted using reliable equipment to study this issue. Consequently, a statistical analysis has been conducted to investigate the correlation between different factors and the noise level to determine the most influential factors that could help draw future intervention plans.
