Element  | Description  | 
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.  |
