Traffic Noise (Indicator)

Traffic Noise

Traffic Noise refers to noise disturbance that the buildings have due to the traffic density in a particular area.

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

How is the Traffic Noise Indicator implemented in the Tygron Platform?

The Traffic Noise Indicator calculates how much buildings in an area suffer from traffic noise.
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.

How is the Traffic Noise Indicator visualised?

The Traffic Noise Indicator can be visualised using an overlay. This Traffic Noise 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.
This overlay becomes available for each stakeholder with an interest in the Traffic Noise Indicator.

Main article:Traffic Noise (Overlay).

Indicator targets

The Traffic Noise Indicator has 1 value for a target:

Number of buildings that suffer from traffic noise disturbance.

The number of buildings that suffer from traffic noise disturbance in a particular area. The lower, the better.

Indicator properties

This indicator is a global indicator. This means the indicator and its target are the same for all stakeholders.
This indicator is represented with a progress bar, representing a scale of 0 to 100% score.
The indicator functions by calculation. The number of buildings that are disturbed by the traffic noise is substracted from the total number of buildings in that area. From this a percentage of the traffic noise disturbance in that area is derived.

The indicator scores per area, for each area a percentage of the traffic noise disturbance is calculated. The score on the indicator as a whole is the average of the scores per area.
Stakeholders with this indicator also have access to the Traffic Noise (Overlay).

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.

Indicator panel

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

• the neighborhood name
• the amount of impacted buildings in this neighborhood
• the total amount of buildings in this neighborhood
• the percentages score per neighborhood of buildings that are not impcated.

Calculation

The pollution is calculated per neighborhood by looking at all buildings in that neighborhood are impacted by the traffic noise over 60 dB.
The total is calculated per neighborhood by looking at all buildings in that neighborhood.
The score is calculated by (the total amount of buildings per neighboordhoord - the polluted buildings in teh neighborhood) / the total amount of buildings in that neighborhood.
The avarage is the scores per neighborhood combined / by the amount of neigborhoods to get a total average score.

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 higher the score, the less heat risk for the elderly there is.

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.

Traffic Noise (Indicator):

1. Select in the editor Current situation from the ribbon
2. Hover over Overlays in the ribbon bar
3. Select the Traffic noise overlay from the drop down menu
4. Hover over the Auto update icon and choose for Reset to Start values (faster) to update your project.
