Zones: HBEFA tab
                                        On the HBEFA tab, you can specify the settings for the HBEFA-based calculation of the cold start excess calculation (Fundamentals: Basis for calculating cold start excess emissions).

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

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

                                                         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.  |
