Assessment of traffic noise
Many road and railway administrations as well as consultancies rely on CadnaA to assess actual, future or modified road networks. Regardless of the size of your projects, CadnaA is perfectly equipped to handle, calculate and present even large areas.
Noise assessment during the construction phase
Although the construction phase is limited in time, the noise emissions are quite often extremely stressfull for the neighbouring residents. Therefore a thorough planning of the construction and the accompanying noise emissions is essential. CadnaA allow our users to define the operating times of any machinery and therefore helps to identify the most critical conditions.
In addition, CadnaA helps to assess the noise in the immediate vicinity of the construction site and the additional acoustic stress caused further away by the construction-related trucks driving on public roads. This way, a sligthly altered construction schedule might prove to strongly reduce the noise levels.
Determination of optimal measures against noise
An essential part of many traffic noise projects is the evaluation of the right measures to mitigate the noise. Of course, it would be best if the regulatory limits are exceeded nowhere, but this quite often is not realistic in dense populated urban areas. CadnaA allows you to calculate and assess many scenarios with different measures so that it is possible to identify the one with the best efficiency. These measures include noise barriers of varying height but also speed restrictions of the traffic, modifications of the street surface or the addition of dampeners to the rails.
A lot of users take advantage of the advanced project organization philosophy of CadnaA which ensures an efficient scenario comparison to test and document any single measure or a combination of them.
