Supporting the Decision of the Road Manager Through Noise Mapping

Noise pollution poses significant challenges for urban infrastructure management, necessitating practical assessment tools such as noise maps. These maps facilitate the visualisation and geo-referencing of noise levels, enabling the identification of areas requiring immediate intervention and long-term strategic responses. Road sections with more than 3 million vehicles per year were selected for measurement. The article presents the results in the form indicated. It obtains an excess of the Long-term Day-Night Average Noise Level (LDWN), affecting approximately 1.899 km² and impacting around 1,200 residents within the exceedance zone. Similarly, the equivalent noise level (LN) exceeds acceptable limits over 1.220 km², affecting an additional 700 residents. At the same time, there were no exceedances of the key noise impact indicators such as a high annoyance (HA), high sleep disturbance (HSD), and ischaemic heart disease (IHD). For areas that exceed the applicable noise standards, a change in traffic organisation was introduced by banning heavy goods vehicles and introducing local speed limits. The changes made have eliminated the noise problem in the urban area. Further anti-noise measures are planned to involve planting plants in the road lane.
