Traffic Noise overlay

The Traffic Noise Overlay is a Grid Overlay which computes the amount of noise in dB(A) for any given location in the 3D World. The calculation takes into account traffic intensities and a number of environmental- and computation parameters to compute the noise impact. It also takes into account objects and terrain features which would block the transmission of noise.

The Overlay only computes noise from traffic. Although a background noise level can be configured, other sources of noise (such as windmills, air traffic, or factories) are explicitly excluded.

Configuration

Main article: Model attributes (Traffic Noise Overlay)

The Traffic Noise Overlay has a number of options which allow it to be configured as desired. A configuration wizard is available.

The following aspects can be configured:

  • Reference speed per vehicle type
  • Noise and noise multiplies per vehicle type
  • Background noise

Calculation

Main article: Traffic noise formula (Traffic Noise Overlay)

The Traffic Noise Overlay performs its calculations based on the Overlay's Attributes, and the Attributes of roads present in the 3D World. The calculations follow the standard rekenmethode 1 (SRM 1), as described on [1]:

Results

The following result types are available as output from the traffic noise calculations:
