- PublicationScenario analysis and noise action planning : modelling the impact of mitigation measures on population exposureThis paper reports on strategic noise mapping research conducted in Dublin, Ireland. Noise maps are constructed for the day–evening–night-time and night-time periods and levels of population exposure are estimated for the same periods. In methodological terms, the research uses the UK’s calculation of road traffic noise (CRTN) method for calculating noise levels in the study area. This method has been adopted as the interim calculation method by the Irish authorities responsible for meeting the obligations set out in the EU Environmental Noise Directive (END). The research also investigates the usefulness of three noise mitigation measures for ‘acoustical planning’ purposes: traffic reductions, speed reductions and erection of acoustical barriers. The results indicate that levels of population exposure during night-time are extremely high relative to guideline limits set down by the World Health Organisation. In addition, the results highlight the significant role that certain noise mitigation measures can play in good ‘acoustical planning’.
1986Scopus© Citations 65 - PublicationStrategic environmental noise mapping : methodological issues concerning the implementation of the EU Environmental Noise Directive and their policy implicationsThis paper explores methodological issues surrounding the implementation of the EU Environmental Noise Directive (END) across Member States. It also highlights future policy implications arising from the analysis which ought to be considered for improving strategic environmental noise mapping in the future. Methodologically, the paper focuses on two key issues relevant to the Directive: calculation methods and mapping methods. For the former, the paper focuses, in particular, on how differing calculation methods influence noise prediction results as well as the value of the EU noise indicator Lden and its associated implications for comparability of noise data across EU states. With regard to the latter, emphasis is placed on identifying the issues affecting strategic noise mapping, estimating population exposure, noise action planning and dissemination of noise mapping results to the general public. The implication of these issues for future environmental noise policy is also examined.

The Harmonoise calculation method is used to calculate noise values for the study area while a Geographical Information System (GIS) is utilised as a platform upon which levels of noise exposure are estimated. Residential exposure is determined for Lden and Lnight while worker exposure is determined for Lden. In order to analyse the potential of traffic management as a noise abatement measure, traffic was redirected from the main residential areas to alternative road links and the revised exposure levels were determined. The results show that the extent of noise exposure in Dublin is considerable, and in relative terms, it is worse for the night-time period. In addition, the results suggest also that traffic management measures have the potential to lead to significant reductions in the level of noise exposure provided that careful consideration is given to the impact of traffic flows on residential populations.

At the outset, the research utilises the CRTN calculation model, LIMA software and GIS to establish areas of poor sound quality. Then a base reference condition of selected roads within noise hotspots is used as a benchmark for assessing the relative impact of the mitigation measures in terms of their ability to bring about reductions in levels of population exposure to noise for both Lden and Lnight. The results demonstrate that in terms of noise action planning, reducing the level of travel demand leads to the most significant reduction in population exposure for Lden and Lnight. They highlight the significant role that noise mitigation measures can play in aiding good ‘acoustical planning’ in the future.
