Περίληψη
This paper proposes a methodology through which advanced
Geographic Information Systems’ (GIS) techniques
are applied in the study of environmental traffic-related
noise. The spatial nature of the factors affecting traffic
noise propagation necessitates the use of GIS, a field of
applications offering by default specialised analytical tools
and functionalities for managing spatial information.
In this respect contemporary GIS tools have been
employed in order to estimate and visualise the impacts of
the above factors, on the noise generated by road traffic.
GIS capabilities such as spatial analysis and geographical
processing, were integrated with proven methods used for
calculating road traffic noise, with the aim to enhance the
study of factors such as distance from the noise source,
screening form intervening obstacles and reflections from
buildings facade.
Separate maps representing the impacts of each individual
factor, on the basic noise level were produced providing
a comprehensive view of traffic noise propagation.
All of the analysis was based on splitting the study area
into a high-density grid, where each grid-cell corresponded
to a reception point. By combining each individual factor’s
contribution for every separate grid-cell, yielded to the
global traffic noise sound field of the entire study area.
