Abstract:

With the viaduct widely used in urban rail transit, the noise problem becomes more and more serious, and attracts more and more attention. This paper briefly introduces the development of the elevated rail transit, analyzes the main types and basic characteristics of elevated rail transit noise, sums up the different mathematical model for the elevated rail transit noise prediction, and finally puts forward the prospects of the future development trend of the elevated railway transit noise prediction method.
