Size of the vehicle fleet
Published (reviewed and quality assured)
Justification for indicator selection
Vehicle ownership and truck intensity are closely related to vehicle use, i.e. the vehicle fleet expands in response to the demand for increased mobility. The size of the vehicle fleet is therefore an important driving factor behind road passenger and freight transport demand and the environmental pressures they cause. Additionally, the total size of a vehicle fleet (combined with its average age - see TERM 33 - Average age of the vehicle fleet) also gives some indication on time needed for new technologies to penetrate into such fleets.

Vehicle ownership is defined as number of road vehicles (passenger cars and two-wheelers) per number of inhabitants. The indicator can be extended to include other specified by passenger transport modes (road busses, coaches, rail, maritime, air), although these are not privately owned.
Freight transport intensity is defined as number of vehicles per unit of GDP
specified by freight transport mode (road, rail, inland, maritime).
The share of diesel cars in the entire passenger car fleet is defined as number of diesel vehicles per total number of passenger cars.
Vehicle ownership is expressed in number of vehicles per 1 000 inhabitants. Freight transport intensity is expressed in number of heavy duty trucks per million Euro of GDP in constant 1995 prices. Dieselisation is expressed in percentage of diesel vehicles in the entire passenger car fleet.
Policy context and targets
The level of vehicle ownership is closely related to car use (and thus the volume of mobility) and - especially in urban areas - also to traffic congestion. Policies aiming at limiting the size and growth of the vehicle fleet might only be found in urban areas, where the number of motorised vehicles is related to increased traffic congestion and the associated higher concentration of air pollutants in the atmosphere.
There are no specific objectives or targets related to the size and composition of the vehicle fleet. Policy objectives are rather set with respect to the average age and to the environmental performance of the fleets.

Is the vehicle fleet expanding?
Methodology for indicator calculation
For passenger transport, vehicle ownership is calculated by dividing the total number of vehicles in each vehicle category (i.e. passenger cars, buses & coaches, two-wheelers, passenger trains) by the number of inhabitants in each country or country group. For freight transport, truck intensity is calculated by dividing the total number of trucks (i.e. light and heavy duty vehicles, freight trains) by the total GDP in each country or country group. The share of diesel passenger cars in the passenger car fleet is calculated by dividing the number of diesel passenger cars by total passenger car fleet.
Methodology for gap filling
Data gaps are filled either by interpolation, in case that data are missing in between reported data, or by using the first (or last) reported value.
