Modeling and Mitigation of Noise on the A23 Motorway Using GIS
Proceedings, 2018
Rendering at the European Directive 2002/49/EC, all EU members have to draw up a strategic noise map for all agglomerations with more than 250,000 inhabitants and for all major airports, roads and railways. A study of environmental impact assessment on motorway A23 in the stretch between Castelo Branco–Alcains (Portugal), based in the impact of the environmental noise, allowed the modeling the noise variation, which can be useful for establishing mitigation measures. The results show that noise model can be a useful tool for the monitoring noise impact in surrounding of motorways.

GIS model for identifying urban areas vulnerable to noise pollution: case study
Frontiers of Earth Science, 2017
The unprecedented expansion of the national car ownership over the last few years has been determined by economic growth and the need for the population and economic agents to reduce travel time in progressively expanding large urban centres. This has led to an increase in the level of road noise and a stronger impact on the quality of the environment. Noise pollution generated by means of transport represents one of the most important types of pollution with negative effects on a population's health in large urban areas. As a consequence, tolerable limits of sound intensity for the comfort of inhabitants have been determined worldwide and the generation of sound maps has been made compulsory in order to identify the vulnerable zones and to make recommendations how to decrease the negative impact on humans. In this context, the present study aims at presenting a GIS spatial analysis model-based methodology for identifying and mapping zones vulnerable to noise pollution. The developed GIS model is based on the analysis of all the components influencing sound propagation, represented as vector databases (points of sound intensity measurements, buildings, lands use, transport infrastructure), raster databases (DEM), and numerical databases (wind direction and speed, sound intensity). Secondly, the hourly changes (for representative hours) were analysed to identify the hotspots characterised by major traffic flows specific to rush hours. The validated results of the model are represented by GIS databases and useful maps for the local public administration to use as a source of information and in the process of making decisions.
Environmental Modelling and Software, 2003
This paper describes a road traffic noise calculation and visualization package TNoiseGIS. It is implemented by utilizing the inbuilt database and spatial routines of a popular commercial Geographical Information System (GIS). The noise calculations can be made according to either of two alternative noise calculation models: the UK CORTN and US FHWA models. These models are applicable for calculating noise levels along highways with free flowing traffic. By applying the inbuilt spatial operations to the geographically located information, noise emission values can automatically be provided for any number of receptor points using either algorithm. The graphical user interface of the GIS simplifies the input of the attributes of the different receptor points and road links. Line and block barriers can be defined and applied with the interpolation technique for calculating traffic noise on receiver points along the back edge of barrier parallel to roadway. As a result, all noise levels behind the barrier can be efficiently estimated. In addition to the calculation of noise emission values for a specified set of receptor points, the variation in the noise levels along the highway can be visualized in the form of noise contours. Such contours provide a visual description of the soundscape and also information on the importance of different factors for soundscape quality. By changing traffic flow parameters such as the localization of planned roads, dwellings, and barriers with different size and location, TNoiseGIS functions as a road traffic noise prediction tool and a tool for planning environmentally friendly road and road traffic noise solutions. The noise calculations and visualization algorithms are implemented by means of scripts that will be made available at a lower cost and also user modifiable.
The Use of GIS in Studying and Modeling Traffic Noise and its Relationship to Land Uses in Riyadh
This study aims to monitor, analyze and model spatial relationships of traffic noise and its intensity in major streets of Riyadh and surrounding residential areas. We shall adopt a mathematical model to obtain noise intensity level from the average number of passing vehicles in the road, their average speed and the percentage of trucks. By using methods of spatial data insertion in GIS system, it was possible to prepare noise maps (continuous area) which shows the nature and pattern of noise distribution in roads and surrounding areas, one set throughout the day and another through peak hours. These maps are useful for delineating areas with high noise level and areas of low noise levels. This information, in turn, is useful for selection of sites for land uses that require low level of noise, such as health facilities, schools, public libraries, etc. By analyzing the relationship between noise and land use of areas surrounding roads, it was possible to know the relationship between the activities and land uses of areas adjoining road, and the level of noise in the roads. The spatial analysis was also useful in understanding the factors that lead to the high noise levels in some roads. The conclusion contains recommendations and planning criteria that may help planners and decision makers to reduce noise levels down to allowable levels, to preserve people's health and comfort and conserve the environment.
The important problem is protection of population from high noise. This problem was discussed in the article. Also in the article was showed the necessity of the noise maps of the city for making correct management decisions is proved. There are presented data on the change in the number of vehicles on the territory of the European Union and Russia, information about noise levels in the territories along the roads in the cities of Russia, the algorithm for generating noise maps of the city. There were estimated noise levels generated by vehicles, in the Central part of the city of St. Petersburg for two scenarios: first on the basis of field studies on the composition and intensity traffic, second – on forecast of limiting vehicle traffic. Conclusion: restriction of movement of vehicles can reduce impact, noise, and values of the maximum concentrations near streets with restricted movement, but at the same time can increase the negative impact of the near streets, where will be redistributed transport stream. The decrease in the maximum ground level concentrations and levels of noise for such a big city like St. Petersburg will contribute to complex of environmental measures: improving fuel, classes environmental performance of vehicles, the development of the road network with traffic organization based estimate of environmental consequences of the proposed activities.
Analysis of Technical Criticalities for GIS Modelling an Urban Noise Map
Geographia Technica
This paper analyzes criticalities and strengthens of a procedure used to model the acoustic map of the vehicular traffic of an urban agglomeration. The research is based on a pilot project for the acoustic mapping of a portion of the city of Palermo (Italy). Simulations indicate that the acoustic climate was in line with expectations and with typical of large Italian cities. The most remarkable result was obtained by an increase in the number of reflections (from two to five), while the influence of the height of the building (from 9 to 18 meters) was negligibleon the order of a few points per thousand. Regarding the analysis conducted with the "Gden Method", acoustic values do not diverge significantly from the other Italian cities, registering values that were, however, the highest in the investigated sample.
Noise Pollution Modelling and Visualisation – the Case Study for the City of Skopje
2016
Noise pollution modelling can be used to provide information about growing noise pollution from the urban traffic. Various methods have been developed that aim at minimizing the noise pollution and improving the environment. Geographic Information System (GIS) can be adapted to gather, analyse and present noise information. The results in this paper demonstrated that most of regions surrounding the main streets are suffering from the noise pollution. As a main contribution of this paper, the first this-kind of study for the city of Skopje, practicing GIS capabilities for presenting noise information, we have produced a general picture of the traffic-induced noise pollution on annual level. The assessment showed that the used method in visualization can provide reliable information about noise pollution in any city or urban region. In this paper, we were focused, as a case study, for the city of Skopje.
Evaluation of traffic noise pollution in a central area of Tehran through noise mapping in GIS
Advances in Environmental Biology, 2012
Although development in transportation system in economic-social fields is considered very useful for societies but nowadays noise pollution is known as one of the main environmental problems while it is the most important sources of pollution in crowded urban districts. Exposing with high noise level in capital cities may be resulted in disorder in daily activities in work place, school, and home because of reducing hearing, social behavior disorders, disorder in sleep, and cardiovascular diseases during a long time. The purpose of the study is going to analyze spatial characteristics of traffic noise in the urban district through measuring sound at 41 stations with residential, medical, educational, commercial-residential, and commercial uses in area 3 of district 6 of Tehran. Parameters including SPL, Lmin, Lmax, Leqav were measured during three intervals ranged from 7-9 am (peak traffic hours), 11-13 (non-peak traffic hours) and 57 pm (peak traffic hours) in fall,2010.
