"Creating a numerical model of noise conditions based on the analysis of traffic volume changes in cities with low and medium structure.
Abstrakt
The subject of this research study is to analyze noise conditions of the selected area in the city of Gdańsk using data related to traffic volume changes during a day. This is because daily distribution of noise levels is much more helpful for noise control and reduction than traditional maps with Lden levels indicated. Calculations are made with the use of a numerical model developed at the Gdansk Univ. of Technology and implemented on the supercomputer PL-Grid infrastructure and using Cad-naA. Obtained numbers are collated with measured ones via city monitoring system. The numerical model of traffic noise and its main sources are briefly characterized. Thanks to the established model of changes in noise level, a full day dynamic noise map are presented as a set of 24 noise maps, one for each hour of the day. Dynamic noise mapping of the main cities can help with faster noise pre-venting and help with traffic calming methods. These two facts are essential to making improvements in living conditions in cities
