Abstract

Reducing noise to acceptable levels is an environmental, social and economic problem of modern cities. To achieve this task, information about the noise conditions of the studied area should be accessible and detailed. That is why the integrated mathematical model for evaluating noise levels at a point of the receiver taking into account the dynamics of vehicles in the flow on the road section, noise reductioneffects, characteristic of modern cities, at its propagation from the source to the receiver and integration of noise levels at the receiving point was developed.This model has allowed taking into account the motion nature of vehicles in the flow depending on the studied road area, the impact of the rugged terrain on the propagation of sound waves from the source to the receiver depending on the position of the receiver, as well as integral evaluation of the noise load levels.The developed model was verified by comparing with the results of experimental studies of traffic flows in two cities. This has allowed to determine the application range of the model and motion features of vehicles in the flow depending on the lane. Mathematical model of traffic noise allows to evaluate noise levels, not only from transport flows on straight roads, but also to simulate the formation of sound fields when approaching traffic lights and intersections.
