Measurements of traffic parameters and conditions in traffic noise research

Abstract

Abstract: The level of traffic noise depends mainly on road traffic parameters such as: traffic volume, share of trucks in traffic and vehicles speed. Traffic conditions determined by such parameters as, for example, the average travel speed, average delays at the intersection and the number of vehicles stops are also important. Their particular importance is revealed especially in the case of bad traffic conditions and a significant reduction of traffic flow. The paper presents selected methods of measuring road traffic parameters, and in particular - traffic conditions on the example of research on their impact on the noise level in the vicinity of the street and intersections. The results of these tests are also presented, determining the impact of such parameters on traffic noise as: instantaneous speed, sectional speed, average delays at the intersection entry, the number of vehicle stops, volume to capacity of the entry ratio.
