Element

Description

Cold start share

Use this attribute to specify the share of cold start for this zone. You can allocate values between 0 and 1 to this attribute.

Tip

If the zone is a cordon zone, for example, it makes sense to allocate value 0 to the zone, because vehicles are usually warm already as they pass a cordon zone.

Calculate cold start excess by area

If the option has been selected, the cold start excess emission is calculated by area.

Calculate cold start excess on paths

If the option has been selected, the cold start excess emission is calculated on paths.
