6 out of 10 kilometres on diesel

The total road traffic volume of Norwegian passenger cars, lorries and buses increased by 0.8 per cent from 2010 to 2011. The share for diesel-powered vehicles increased from 56 to 59 per cent.

Road traffic volumes, by main type of vehicle. 2005-2011. Million kilometres

Road traffic volumes, by type of fuel. 2005-2011. Million kilometres

Diesel-powered lorries, buses and passenger cars were driven a total of 25.4 billion kilometres in 2011, while petrol-powered vehicles in total were driven 17.4 billion kilometres. Thus, the diesel-powered vehicles’ share increased from 56 to 59 per cent from 2010 to 2011. Vehicles powered by fuels other than diesel and petrol only had a 0.1 per cent share of the total road traffic volume in 2011.

Passenger cars with 77 per cent of the mileage

Norwegian passenger cars, goods road vehicles and buses were driven a total 43 billion kilometres on Norwegian and international routes in 2011; 0.8 per cent more than the year before. Passenger cars were driven 33 billion kilometres, or 77 per cent of the total mileage; the same as in 2010. The figures showed a slight decrease in mileage for small lorries and buses in 2011 compared to the previous year, while there was an increase for large lorries.

Road traffic volumes, by main type of vehicle and home county of owner. 2011. Million kilometres

Car owners from Oslo and Akershus accounted for 25 per cent of kilometres driven

Passenger cars, lorries and buses with owners living in Akershus and Oslo were driven 5.8 and 5.3 billion kilometres in 2011 respectively. Their share of the total road traffic volume in 2011 was 26 per cent. Vehicles from Hordaland and Rogaland counties had a 8.0 and 7.6 per cent share of the total driving with Norwegian vehicles respectively; almost the same as last year.

Decrease in the average mileage for passenger cars

The average mileage for all passenger cars was 13 000 kilometres in 2011, compared with 13 300 kilometres the previous year. Buses performed an average of 30 100 kilometres, and heavy lorries 36 700 kilometres. The annual average driving distance for road tractors was 67 300 kilometres.

New cars are driven the most

New cars are generally driven more than older cars. Utility vehicles, such as road tractors, lorries and buses, are driven considerably longer than other types of vehicles in their first five to ten years. After a while, however, the average yearly mileage of utility vehicles more closely corresponds to the average mileage of other types of vehicles. Passenger cars that are newer than five years old were driven an average of 16 000 kilometres in 2011. Heavy lorries that are newer than five years old were driven an average of 58 000 kilometres in 2011, while the annual average driving distance for newer road tractors was 85 000 kilometres.

Estimating road traffic volumes

The distances covered by vehicles are calculated from odometer readings collected at mandatory roadworthiness tests. The statistics cover vehicle-kilometres performed by Norwegian passenger cars, road goods vehicles, buses and coaches in Norway and abroad. Vehicle-kilometres performed by foreign vehicles on Norwegian roads are not included. Vehicles with special licence plates and vehicles registered prior to 1 January 1960 are not included in the statistics. Changes in traffic volumes caused by economic or social trends may take some time to be registered in the statistics due to the use of odometer readings as the main data source (see About the statistics ).


Road traffic volumes by county and municipality

The distribution of road traffic volumes by the home county and home municipality of the vehicle owners is to a large degree a result of the number of local inhabitants, with some variations due to differences in average annual driving distances and average number of vehicles per inhabitant between the counties and municipalities. However, it should be noted that vehicles may be driven in other places than where their owners are located. For instance, vehicles owned by leasing companies or large transport or service companies will usually be registered to the main offices, even though the vehicles are used in other parts of the country. At municipality level, this particularly affects the traffic volumes in Bærum in Akershus, where several of the large leasing companies in Norway are located.
