Input attributes for calculation

Prior to emission calculation, values must be entered for the following attributes:

Network object	Attribute	Description
Link	Urban	This attribute specifies whether a link is regarded as urban or rural during the calculation. Notes Your allocations should be based on the COPERT scheme (Fundamentals: Basis for calculating warm emissions). You can set the attribute value In the Environment tab of the respective link window or in the Link list. The attribute is not directly related to the set fleet compositions Urban, Rural and Highway.
Zone	Cold start share	Use this attribute to specify the share of cold start separately for each zone. In the Zones list and in the HBEFA/COPERT tab of the Edit zone window, you can allocate values from 0 to 1 to the 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.
