Optional Traffic NO2 (Air polution effect) overlay

The Traffic NO2 Overlay is a Grid Overlay which computes the impact of traffic air pollution (in μg/m³ NO2) for any given location in the 3D World. The calculation takes into account the amounts- and types of traffic, and the distance from the source of emission.

The Overlay only takes into account NO2 emissions from traffic. Other sources of emissions (such as air traffic of factories) are explicitly excluded.

Configuration

Main article: Model attributes (Traffic NO2 Overlay)

The Traffic NO2 Overlay has a number of options which allow it to be configured as desired. A configuration wizard is available.

The following aspects can be configured:

  • Emissions per vehicle type both in motion and in traffic jam
  • Constants for road-based dilution factors

Calculation

Main article: Traffic NO2 formula (Traffic NO2 Overlay)

The Traffic NO2 Overlay performs its calculations based on the Overlay's Attributes, and the Attributes of roads present in the 3D World.

Results

The following result types are available as output from the traffic NO2 calculations:
