Noise reduction potential with speed reductions

The introduction of 30 km/h speed limits is increasingly being considered as a noise abatement measure. Experiences from case studies show strongly scattering acoustic effects of such speed reductions. This is mainly due to the highly complex transition area between rolling and driving noise, as well as the significant influence of driving behavior.

Since conventional emission models are not tailored to the low speed range, no reliable calculation of emissions has been possible so far. Therefore, within the framework of the national research project VSS 2012/214, a model was developed by Grolimund + Partner AG, which specifically maps the noise emissions of road traffic in the low speed range and thus allows a reliable calculation of the noise reduction potential. With our know-how and our large network, we can advise you as experts on the topic of "Tempo 30" and support you in the planning of concrete measures for noise reduction. Based on your specific initial situation, we can acoustically model and evaluate the noise impact for a desired speed reduction. As a result, you will receive a fact sheet from us with the compilation of the results on the noise effect of your target situation, including a statement.
