Objective. On the basis of analysis of the latest requirements of the EU and Ukraine, to establish the maximum allowable motor vehicle sound levels that can be recommended for use in calculations of acoustic characteristics of motor traffic flows.
Research object and methods. Technically allowable motor vehicle sound levels; analysis of regulatory documents: statistical.
Research results and discussion. According to the results of the analysis of the latest technical requirements of the EU and Ukraine to external maximum motor vehicle sound levels, allowable sound levels for motor vehicles (passenger cars, minibuses, buses, trucks) have been recommended for calculating acoustic characteristics of motor traffic flows. The application of the proposed levels in the calculations of acoustic characteristics of motor traffic flows will improve the quality of forecasting the acoustic situation in residential areas adjacent to roadways and managing the risks of developing cardiovascular diseases associated with motor traffic noise.
Conclusions. When calculating acoustic characteristics of motor traffic flows (before year 2024), if the intensity and composition of the motor traffic flow is known, it is recommended to use the following acoustic characteristics of motor vehicles: for cars – 72.7 dBA; for minibuses – 72.3 dBA; for buses – 76.3 dBA; for trucks (N2) – 75.5 dBA; for trucks (N3) – 79 dBA.
When calculating acoustic characteristics of motor traffic flows (starting from year 2024), if the intensity and composition of the motor traffic flow is known, it is recommended to use the following acoustic characteristics of motor vehicles: for cars – 70.7 dBA; for minibuses – 71.0 dBA; for buses – 75.3 dBA; for trucks (N2) – 74.5 dBA; for trucks (N3) – 77.3 dBA.
