Correlation of Traffic Noise Parameters in Queensland
The current available approaches for predicting road traffic noise level indicators rely solely on Linear Regression models that use either LA10(18H) or LA10(1H) as an input variable. This paper extends the prediction scope of regression models to include important indicators and additional road traffic factors as input variables and compares the performance of several machine learning regression methods.
