Analysis and Management of Current Road Traffic Noise

Road traffic noise is one of the major environmental pollutants in cities around the world that continues to increase over the years despite the implementation of regulatory policies. The lack of engagement of national governments, the use of different or inadequate methodologies and the absence of implementation of measures to control road traffic noise are some of the causes why the population exposed to noise has not been reduced. There are a large number of recommendations, methodologies and procedures for adequate road traffic noise analysis and management in the scientific literature. The aim of this paper is to analyse the main findings of recent years with the objective of highlighting the current acoustic situation and to provide tools that can reverse it. Development of accurate noise analysis methods is close to reality. However, greater engagement and control by the authorities is needed for the implementation and efficiency of noise measures.
