  • you've learned how to adjust your project in order to make the indicator functional.


General

The traffic health impact indicator provides a combined output for the built-in calculated overlays for traffic noise emissions and traffic NO2 emissions. It calculates an absolute score based on the percentage of housing units suffering from either form of disturbance. This indicator can be used in project which deal with:

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

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 protest indicator.

The indicator panel shows the following information:

  • The name of the neighborhood
  • The amount of houses (related to the total amount of houses) which have more than 50.3 dB of noise.
  • The amount of houses (related to the total amount of houses) which have more than 1 ug/m3 of NO2 impact.
  • The score per neighborhood

Calculation

The indicator counts the total amount of housing units, and the amount of housing units that are affected by either noise or NO2 disturbance from traffic.

Score

The score of the indicator is the average of the percentage of houses not affected by noise pollution and the percentage of houses not affected by NO2 pollution. Both metric are counted with equal weight.

Additional configurations

The indicator requires the inclusion of both the traffic noise overlay and the traffic NO2 overlay.
