Noise Barrier in Intra-City Transportation

Abstract

Rapid urbanization, migration and population growth induced demands exceed the carrying capacity of the cities and thus the existing urban infrastructure becomes insufficient. Developments in social life in the metropolitan cities, technological progresses and the related increase in the movements caused introduction of noise to the people’s lives. Increase in the length and number of the highways for intra-city transportation in addition to changing life styles cause an increase in the densities, which results in noise pollution in the cities and on the main roads. Noise preventing structures are used to prevent/reduce the noise pollution caused by intra-city transportation. Among these structures, noise barriers and plants as live materials play an active role. In this study, noise sources in the intra-city transportation are described and effectiveness of the measures to reduce noise pollution is discussed.
