Resumen
The main purpose of that study was an experimental effort to determine the correlation between various traffic and meteorological parameters and sound pollution created as a result of the that traffic.This paper presents the research results of traffic noise level recorded in the street which is a part of the road system of Bielsko-Biala city. Measured noise data were compared to the registered traffic flows, share of heavy vehicles in the traffic flow and to the velocity of vehicles in the traffic flow. To determine the vehicle velocity from recorded video a velocity detection algorithm was used. It was created based on the MatLab package and allows to determine the vehicle velocity in the movie frame.The studies are at the first step towards obtaining general assumptions related to the work leading to the formulation of a semi-empirical model of acoustic impact of traffic flow.The paper shows the strong correlation between traffic flow and sound level. At the same time, it shows a slight impact of the structure and the speed of vehicles on the level of noise. However, weather conditions don?t have any influence on the created sound pollution.
