To support the emission calculations a project has been carried out by DTU
Transport, in order to provide fleet and annual mileage data for the vehicle
categories present in COPERT IV (Jensen and Kveiborg, 2011). The latter
source also provides information of the mileage split between urban, rural
and highway driving. The respective average speeds come from The Danish
Road Directorate (Ekman, 2005). Additional data for the moped fleet and
motorcycle fleet disaggregation information is given by The National Motorcycle
Association (Markamp, 2011).
In addition data from a survey made by the Danish Road Directorate (Hansen,
2010) has information on the total mileage driven by foreign trucks on
Danish roads in 2009. This mileage contribution has been added to the total
mileage for Danish trucks on Danish roads, for trucks > 16 tonnes of gross
vehicle weight. The data has been further processed by DTU Transport; by
using appropriate assumptions, the mileages have been backcasted to 1985
and forecasted to 2010.
