What is the Traffic Noise overlay?

Active Traffic Noise overlay

The Traffic Noise overlay is an Overlay which displays the impact of traffic noise in different colors for the project area. Based on traffic flow, distance and several computation parameters a grid is calculated for the project area. Note, this overlay only shows the impact of traffic noise on top of a background value of 48 Decibel. Influence of other sources (e.g. windmills, air traffic, factories, etc) is excluded.

Calculations

The calculations follow the standard rekenmethode 1 (SRM 1), as described on [1]

Adding and removing

Template:Editor ribbon

Adding and removing overlays is a generic process, however, certain overlays are dependent on other assets being present too, such as indicators, terrains, vacancy, images, etc. For more information please refer to the respective main articles for the specific overlays.

How to add the Traffic Noise overlay:
  1. Select in the editor '3D World' from the ribbon
  2. Select 'Overlays' > 'Edit overlays' from the ribbon bar
  3. Select the Traffic Noise overlay from the drop down menu on the bottom of the left panel
  4. Select 'Add' from the bottom of the left panel
  5. The overlay icon will now appear under the mini map
How to remove an overlay:
  1. Select in the editor '3D World' from the ribbon
  2. Select 'Overlays' > 'Edit overlays' from the ribbon bar
  3. Select the desired overlay'*' from the list of active overlays'**' on the left panel
  4. Select 'remove' from the bottom of the left panel
  5. Confirm the removal in the pop up confirmation message

Sometimes it can be convenient to duplicate an already existing overlay. To do so, follow the steps for removal, but select 'Duplicate' in stead of 'Remove'.

The overlay calculations are based on Standard Calculation Method 1 (SRM1) as defined by the dutch government: wetten.overheid.nl
