Abstract

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 Bogotá and was established on the basis of the fit of single Li,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 Bogotá. The approach used is promising for further investigations of urban traffic noise given the traffic conditions in these systems.
