Traffic Noise (Indicator)

General

What is the Traffic Noise Indicator?

Traffic Noise refers to noise disturbance that buildings can have due to the traffic density in a particular area. The Traffic Noise Indicator calculates how much houses in a neighborhood suffer from traffic noise.
This indicator can be used in projects which deal with:

• health and livability considerations
• development of housing solutions
• traffic flow adjustments

The Traffic Noise Indicator uses the Traffic Noise Overlay for its calculation. This overlay displays the average noise that is produced for each part of the project detail area, giving an indication of the noise disturbance in that area. See for more information the Traffic Noise (Overlay) page.

This Excel indicator can be downloaded from the Tygron Index. Read on to find out more about the indicator's calculation method and how to set it up in your project.

Note: this indicator is the same as the default Traffic Noise indicator from the Indicator menu in the Tygron Platform.

Indicator panel

The indicator panel (see the image on the right) shows in a table per neighborhood:

• the neighborhood name
• the amount of impacted houses in this neighborhood
• the total amount of houses in this neighborhood
• the percentage score per neighborhood of houses that are not impacted.

Calculation

The pollution is calculated per neighborhood by looking at all buildings in that neighborhood that are impacted traffic noise.
With traffic noise is meant more than 60 dB noise. The score is then calculated by (the total amount of buildings per neighborhood - the polluted buildings in the neighborhood) / the total amount of buildings in that neighborhood.
The average is the scores per neighborhood combined divided by the amount of neighborhoods.

Score

The score is represented in a progress bar, with a scale from 0 to 100%. Determine if you want to calculate the absolute or reative score. The Indicator scores based on the number of buildings that suffer from traffic noise per area. A lower number of buildings that are disturbed by the traffic noise means a better score.

Additional configurations

For this indicator to function, only the Traffic Noise overlay has to be added to the project, see below for the steps.

If desired the limit of 60dB can be changed in the excel to a different number of dB to be the guideline of impacted buildings.

Add the Traffic Noise overlay

When the indicator is added to the project, an error message can be given. This is due to the missing Traffic Noise overlay in the project. Read below on how to add this overlay to the project.
