Studies and assessment of transport noise in Poznan

Abstract

In many cities in Poland, because of the lack of ring roads, the main traffic routes of state roads go through the cities affecting local and regional traffic. This causes high traffic and also many undesired effects for inhabitants such us environmental pollution with fumes, vibrations of buildings, high level of noise and increase of accidents. This article presents results of measurements of volume of traffic and noise level in selected traffic routes in Poznan. For the research the sections of roads and crossings that belong to state roads and important urban roads of Poznan were selected. The research was conducted according to recommendations included in the regulation of the Minister of the Environment of 16 June 2011 on requirements for conducting measurements of the levels of substances or energy in the environment by administrators of road, railway, tram line, airport or sea port. In most of the streets of Poznan, where measurements were made, registered equivalent sound levels exceed permissible levels defined in the regulation of the Ministry of the Environment about permissible noise levels in the environment. Equivalent sound levels registered at defined measurement points show values in scope between 53 and 78 dB.
