Silence is the main noise management system for the Dutch highways and is used by the Dutch Ministry of Transport. The Silence system comprises IT infrastructure, environmental data, noise management software, an organisation, procedures and maintenance. Typical noise management system tasks involve data management, setup noise management software, software customisation, performing calculations and analyses and a proper maintenance cycle. In 2010 the new noise management system will become available and everything will be in place for (evaluation of) noise policy and the next round of EU noise mapping in 2012. This paper provides insight in the activities needed for setting up and maintaining large complex noise mapping systems including strategic tools e.g. noise emission ceilings, implementing noise policies and what-if analyses.
