The Governing Board of the City of Cartagena this morning initially approved the Strategic Noise Map of the urban agglomeration of Cartagena, which was presented to the media by the Town Planning and Environment, and Joaquin Segado Palazón Carolina.
The main conclusions that has produced this map point to traffic with the dominant noise source in Cartagena.
Their highest levels recorded in the wide avenues, with intercity routes, entrances to the city, connections between neighborhoods and other main roads.
During the day (from 7 am to 7 pm), a total of 4,300 people (3.5 percent) exposed to levels above 65 dB (acoustic quality objective for the period day), for evening (from 7 pm to 11 pm) are 2,500 (2 percent) who are exposed to levels above 65 dB, in the period of night (between 11 pm and 7 in the morning), are 4,000 people who are exposed to levels above 55 dB (acoustic quality objective for the night).
Throughout the whole day, people exposed to levels above 65 decibels reach the 5,800 inhabitants, down 4 percent.
It is the opinion of the council and technicians have developed a map, a similar figure to that recorded in other Spanish cities with the largest population and is within normal, although most cities with a population similar to that of Cartagena are currently preparing their corresponding maps.
As explained by the councilors, the Strategic noise map is a cartographic representation of noise levels in the various areas of the city that allows to know the number of people exposed to each noise level.
This Strategic Noise Map of the city of Cartagena has been developed in order to meet the provisions of the Noise Act regarding the assessment and management of environmental noise that require municipalities with more than 100,000 inhabitants to develop this type document in 2012.
The document will be on public display for a period of one month for submission of technical arguments.
SCOPE OF WORK
The territorial scope of the Strategic Noise Map is the main urban area, defined by the criteria of number of inhabitants, population density and proximity of suburbs.
The Cartagena conurbation covers a polygon perimeter of 34 kilometers and encloses an area of approximately 23 square kilometers.
In this area live 122,796 inhabitants (approximately 56% of the total population).
The boundaries that define this polygon are:
- To the south, the port of Cartagena, the east, and the round cross Torreciega neighborhoods, Santa Lucia and I Campano. - On the north, the Santa Ana Residential Estate - To the west, the urbanization of La Vaguada .
Noise sources that have been considered in developing the noise map, are those established by the Royal Decree implementing the Law of Noise:
- Road traffic (including major routes.) - Air-Traffic Railway Traffic. - Industrial Noise.
The periods in which the evaluation was made of existing noise levels are as follows:
- Day: Between 7'00 and 19'00 hours (Lday) - Afternoon: Between 19.00 and 23.00 hours (Levening) - Night: Between 23'00 and 7'00 hours (Lnight ) - Day-Evening: All day (Lden).
Methodology A
The development of the noise map of Cartagena is organized in two phases, the first to be concluded last year (corresponding to some of the neighborhoods of the north and east of Cartagena) and a second that ended last May ( includes the rest of the city).
The noise map was drawn by a predictive software (a software simulation) that handles a very abundant and diverse information.
To name a few variables that account have included:
- Terrain. - Number and type of vehicles on various city streets. - Speed ​​of movement. - Type asphalt-height buildings. - Predominant uses of the buildings. - Characteristics of the facades of the buildings (reflection). - Resident population in each building. - noise maps of major axis-type trains, velocity and step frequency.
Also, there have been about a thousand measurements of noise levels in public places, some of them lasting more than 24 hours, in order to validate the results provided by the software.
The end result is a collection of maps shown by isophones lines, represented by different colors, noise levels in each area of ​​the city at different intervals of the day.
