Analysis of the Influence of Urban Road Traffic Flow Parameters on the Acoustic Environment

摘要

On the basis of measuring the traffic noise data of Shenyang urban sub road in Shenyang, this paper starts with the speed and traffic flow, analyzes the data by SPSS statistical analysis software, and uses linear fitting, statistical analysis and other methods. The two factors were analyzed, and the conclusions were drawn: First, the traffic noise and speed are approximately linear in a certain speed range, that is to say, the noise value increases with the increase of the speed of the vehicle. Second, the logarithmic positive correlation between traffic flow and traffic noise is that, with the increase of flow rate, the noise value at the initial stage increased significantly. Then when traffic reaches to a certain number, the increasing trend is not very obvious. And the road traffic noise model was established by using Cadna/A software, and the spatial distribution of road traffic noise was analyzed by the software.
