Strategies for noise action plans

Abstract

Following the requirements of the Environmental Noise Directive, Noise Action Plans should have been produced. The plans are supposed to build on two important pillars: the strategic noise maps and the consultation with the local residents. In some cases, the plan is considered as a mere statement of the long term policy of the authority under concern. In other cases, it is set up as an implementation plan with clear and measurable targets. Also the focus varies: only the highest noise levels could be attacked or the large numbers of exposed citizens, or even the overall annoyance. Target noise levels may lead to confusion both for local decision makers and citizens. Also, the preservation and possible creation of quiet areas can be envisaged. The use of an equal annoyance indicator helps to set the targets in the right perspective. Translation into different levels of quality of life is recommended. In terms of cost and benefits, the options for city councils are very limited. Due to a lack of European legislative power, cities tend to set their own rules, e.g. for road vehicles. Several initiatives to propose toolkits for action plans, comparable to the best practice guide for noise mapping, are welcomed but require harmonization and dissemination.
