A Computer Model for Determining the Temporal Distribution of Noise from Road Traffic,

摘要

A new method is described for computing the temporal distribution of noise from freely flowing traffic,which is much faster than Monte Carlo models of similar sophistication. Validation studies indicate that the standard deviation of the observed values from the computed values of L10, L50and L90are 1.1, 1.3and 1.9dBA respectively. The computer model can be readily extended to synthesize traffic noise in urban roadway networks and,in principle,noise from different transport modes. It is intended to develop the modelling technique further to construct an urban noise model incorporating complex roadway networks and ultimately various transport modes. (Modified author abstract)
