Modeling urban traffic noise with stochastic and deterministic traffic models

Applied Acoustics, 2013
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 Li,17sec noise functions for different types of vehicles.

A statistical model of traffic noise

Applied Acoustics, 1968
Traffic noise recordings have been analysed and presented in the form of graphs of the percentage of time during which the noise remains between certain levels against the levels involved. It has been established experimentally that observations presented in this form approach a Gaussian distribution.

Urban daytime traffic noise prediction models

Environmental Monitoring and Assessment, 2009
An evaluation was made of the acoustic environment generated by an urban highway using in situ measurements. Based on the data collected, a mathematical model was designed for the main sound levels (L (eq), L (10), L (50), and L (90)) as a function of the correlation between sound levels and between the equivalent sound pressure level and traffic ...

Traffic Noise Modelling Considering Traffic Compositions at Roundabouts

2021
As the traffic volume is increasing in urban areas, their major effect can be seen in terms of noise near roundabouts. An effort has been made in this work to evaluate the noise level near a roundabout in terms of certain noise-level descriptors such as Leq, L10, L50 and L90 to estimate the maximum and pervasive noise climate existing at the ...

Noise properties in the Nagel-Schreckenberg traffic model

Physical Review E, 2001
The jamming transition in the stochastic traffic cellular automaton model of Nagel and Schreckenberg is examined. The behavior of the power spectrum is analyzed. Numerical results are presented. Satisfactory analytical approximations are established in both low frequency and high frequency regions.

Simplifying prediction method for traffic noise based on FHWA traffic noise model

2011 International Symposium on Water Resource and Environmental Protection, 2011
Based on analyzing and discussion of Federal Highway Administration (FHWA) traffic noise model, a new simplifying prediction method, which shows the connection between the traffic noise increment with increase of traffic volume, was put forward. In addition, the applications of the simplifying prediction method and its application qualifications were ...

Traffic Generated Noise Models

Transportation Engineering Journal of ASCE, 1977
In-situ noise level surveys have become an important part of environmental impact studies that have been prepared for proposed new and improved roadways. Since these studies are very costly, it is imperative that the engineer provide the client, the road user, and the taxpayer with information that will aid them in evaluating proposed improvements.

Road traffic noise: self-reported noise annoyance versus GIS modelled road traffic noise exposure

Journal of Environmental Monitoring, 2011
self-reported road traffic noise annoyance is commonly used in epidemiological studies for assessment of potential health effects. Alternatively, some studies have used geographic information system (GIS) modelled exposure to road traffic noise as an objective parameter. The aim of this study was to analyse the association between noise exposure due to

A simulation model for urban traffic noise

The Journal of the Acoustical Society of America, 1999
Urban traffic noise is studied by a simulation model whose main features are the following: effects of traffic lights, speed limit, possibility of vehicles overtaking, and driving styles. In the model there is a basic assumption about driver’s behavior (‘‘follow the leader’’), considering the case of straight and level road with two lanes for every ...

Fuzzy modeling of traffic noise annoyance

Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat. No. 01TH8569), 2002
This paper presents a fuzzy rule-based model for the prediction of traffic noise annoyance. Several inference schemes are compared for their performance in prediction capabilities as well as in speed. It is shown that the fastest implementation does an equally good job, after optimization of certainty degrees attached to the rules.
