Noise maps from traffic sources in Dublin Region

Road Source Noise Model The dataset contains the noise model results for the Dublin Region showing population exposure to sound from traffic sources. The noise maps show colour coded areas in Dublin based on sound levels in 5 bands. These increment in 5 decibels. The night time band starts at 50 decibels and the 24 hour band starts at 55 decibels. There are two categories of sound sources mapped all roads and major roads (roads with more than 3 million vehicle passages per year). Traffic volumes are averaged to an hourly traffic count over a typical 24 hour day. The supporting dataset Total Traffic Volumes and Road Centrelines for Dublin City is also published on Dublinked. Dublin City Council revised the first set of 2007 road source noise maps to produce the current maps for June 2012. The 2012 Revision of Noise Maps and Action Plans are available to download in kml format at

Purpose of Collection The relevant noise mapping bodies are required to produce strategic noise maps every 5 years under EU Directive 2002/49/EC relating to the assessment and management of environmental noise (END). Rail sources are mapped by Irish Rail and the Rail Procurement Agency.
Use Constraints Strategic maps are not to be used to address local noise nuisances such as neighbourhood or domestic noise abuse. Caution should be exercised when comparing 2012 and 2007 noise maps having regard to a decrease in traffic volumes, availability of more robust datasets, the use of amended calculation methods and improved software and the revision of major road status from 6 million to 3 million vehicle passages per year. Noise maps for rail sources within the Dublin City Council area produced by Irish Rail and the Rail Procurement Agency produce. Industrial point sources are not mapped due to lack of strategic impact on the overall sound environment, by agreement with the EPA. Population exposure statistics have been amended to take into account the change in population identified by the 2011 Census.
