TLDR
In this paper, the noise emitted from steady statistically stationary traffic flow is studied analytically from the point of view of a stochastic acoustic model, in order to relate the noise field in terms of the details of the flow, and the acoustic characteristics of the vehicles therein.About:

Journal ArticleDOI
Effects of headway distributions on second order properties of traffic noise
D.E. Blumenfeld,G.H. Weiss +1 more
TL;DR: In this article, the authors considered the effects of more general headway distributions on the variance of the sound pressure level, the autocorrelation function, and the spectral density, and they showed that for a fixed traffic density increasing the order of the distribution decreases the variance and tends to emphasize higher frequencies in spectral density.
Mathematical Modeling of Environmental Noise Impact
K. Rawat,V. K. Katiyar +1 more
TL;DR: In this article, the authors proposed a road traffic noise model that predicts well the traffic noise near highways so that the people living near highways who are highly exposed by everyday traffic noise can be protected from noise exposure to some extent.
Journal ArticleDOI
Method of predicting Leq created by urban traffic
TL;DR: The time-averaged overall mean-square sound pressure created by statistically stationary traffic travelling a finite, straight road segment is determined explicitly and this result is extended to a system of roads by using digital simulation.
Journal ArticleDOI
Shielding of noise from statistically stationary traffic flows by simple obstacles
TL;DR: The effect of neighbouring, smooth obstacles on the sound generated by statistically stationary traffic movements is analysed for simple but realistic practical situations and extremes of absorption are used to gauge their significance.
Journal ArticleDOI
Theoretical foundations of some problems of environmental acoustics
TL;DR: In this paper, a description of the sound field of moving sources, in terms of the average intensity of sound over time, is given under the assumption that the sources are moving at a constant speed, near to a flat surface with uniform cover.

On kinetic waves, II . A theory of traffic flow on long crowded roads
M J Lighthill,G B Whitham +1 more
TL;DR: In this paper, a functional relationship between flow and concentration for traffic on crowded arterial roads has been postulated for some time, and has experimental backing, from which a theory of the propagation of changes in traffic distribution along these roads may be deduced.
Journal ArticleDOI
On kinematic waves II. A theory of traffic flow on long crowded roads
TL;DR: The theory of kinematic waves is applied to the problem of estimating how a ‘hump’, or region of increased concentration, will move along a crowded main road, and is applicable principally to traffic behaviour over a long stretch of road.
Journal ArticleDOI
Subjective response to road traffic noise
I.D. Griffiths,F.J. Langdon +1 more
TL;DR: In this article, a study consisting of acoustic measurements at fourteen sites in the London area and 1200 interviews dealing with the effects of the noise conditions prevailing at each of these sites has been carried out with the object of developing acceptability criteria for traffic noise from roads in residential areas.
Journal ArticleDOI
The evaluation of noise from freely flowing road traffic
D.R. Johnson,E.G. Saunders +1 more
TL;DR: In this article, a survey of the noise emitted by freely flowing traffic has been made on sites ranging from motorways to urban roads and the results provide an indication of present-day traffic noise conditions against which future comparisons may be made and also show how basic variables such as traffic density, speed and composition, and distance from the roadside affect the observed patterns of noise.
