Abstract: The article presents a noise forecasting model around the A motorway on the Komorniki – Krzesiny section. The model was developed based on sound level recordings in three stages of research related to the motorway’s operational phases (acoustic background measurement – without vehicle traffic, measurements after the Komorniki – Krzesiny section was opened to traffic, and noise measurements after the launch of the new Nowy Tomyśl – Konin motorway section). The developed model was verified based on the actual number of vehicles that passed through the Komorniki – Krzesiny section on a randomly selected day and time.1. INTRODUCTION
Among the many types of human activity that contribute significantly to the degradation of the natural environment, transport, especially road transport, occupies a significant place [4]. The environmental threat caused by motorization is currently considered one of the most noticeable nuisances of civilization development. This is determined by the mass scale of vehicles, the intensity, and the universality of their use. The development of motorization, driven by its attractiveness, has contributed relatively quickly to the imbalance in the human natural environment. It is currently estimated that in cities, a 10% increase in traffic causes a doubling of travel time, an increase in fuel consumption and toxic substance emissions by about 25%, and a decrease in bus communication speed by about 30% [7]. In terms of noise impact on the environment, noise monitoring studies conducted by the Environmental Protection Inspection authorities have shown that the number of people threatened by noise in Poland is between 13 and 15 million, and during the daytime, the average equivalent sound level in the centers of large cities exceeds LAeq, day = 70 dB [3].
The article presents a model for forecasting sound levels on the Komorniki – Krzesiny motorway section, which is a fragment of the toll A Świecko – Kukuryki motorway. The model was developed for the specific location of the discussed motorway section: the roadway is situated in a cutting and runs through the agglomeration areas of the city of Poznań, Luboń, and Komorniki.
