Traffic health impact (Indicator)
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 average of the percentages of housing units not affected by each disturbance. This indicator can be used in projects that deal with:
- health and livability considerations
- development of housing solutions
- traffic flow adjustments
This Excel indicator can be downloaded from the Public GeoShare. 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 shows the following information:
- The name of the neighborhood
- The percentage of houses with noise levels exceeding 50.3 dB.
- The percentage of houses with NO2 impact exceeding 1 ug/m3.
- The score per neighborhood
Calculation
The indicator counts the total number of housing units and those affected by traffic-related noise or NO2 disturbances.
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 metrics are counted with equal weight.
Additional configurations
The indicator requires the inclusion of both the traffic noise overlay and the traffic NO2 overlay.
