摘要：

This paper presents the development and evaluation of a stochastic dynamic traffic noise prediction model based on noise curves for vehicle classes and their speed. The model was tested on urban two-lane roads in the city of Bogota and was established on the basis of the fit of single L-1.17sec noise functions for different types of vehicles. The model showed a slightly better fit than was found in four deterministic models that are highly internationally recognized. Additionally, a deterministic model was derived contextualized to the city of Bogota. The approach used is promising for further investigations of urban traffic noise given the traffic conditions in these systems. (C) 2012 Elsevier Ltd. All rights reserved.
