Stated choice valuation of traffic related noise [PDF]

open access: yes, 2006
This paper reports a novel application of the stated choice method to the valuation of road traffic noise. The innovative context used is that of choice between apartments with different levels of traffic noise, view, sunlight and cost with which ...

Dynamic estimation of urban traffic noise: Influence of traffic and noise source representations [PDF]

open access: yesApplied Acoustics, 2008
The need for traffic noise prediction models that take traffic dynamics into account has been recently shown for urban areas. Such models couple a dynamic representation of traffic with noise emission laws. The contribution of the paper is to test different traffic and noise source representations for LAeq and statistical levels estimation.

Development of a traffic noise prediction model for an urban environment

open access: yesNoise and Health, 2014
The objective of this study is to develop a traffic noise model under diverse traffic conditions in metropolitan cities. The model has been developed to calculate equivalent traffic noise based on four input variables i.e. equivalent traffic flow (Q e ),

Estimating the effect of semi-transparent low-height road traffic noise barriers with ultra weak variational formulation [PDF]

open access: yes, 2011
The ultra weak variational formulation (UWVF) approach is used to study the effect of semi-transparent road traffic noise barriers of limited height. This numerical method is extended to simulate sound propagation through a porous medium, based on the ...

Theoretical Comparison of the Effects of Different Traffic Conditions on Urban Road Traffic Noise

open access: yesJournal of Advanced Transportation, 2018
Road traffic noise is one of the most relevant sources in the environmental noise pollution of the urban areas where dynamics of the traffic flow are much more complicated than uninterrupted traffic flows.

Predicting Hourly Traflc Noise from Traflc Flow Rate Model: Underlying Concepts for the DYNAMAP Project

open access: yesNoise Mapping, 2016
The DYNAMAP project aims at obtaining a dynamic noise map of a large residential area such as the City of Milan (Italy), by recording traffic noise from a limited number of noise sensors.

Three-dimensional visualisation of traffic noise based on the Henk de-Klujijver model

open access: yesNoise Mapping, 2023
Visualisation of road traffic noise is vital for traffic noise planning policies. Several factors affect the noise from road traffic with physical and environmental conditions. Collecting noise levels around the world is not a possible task.
