List of OECD countries by road network size

Map indicating the amount of roads per 100 km² of land area for each country

The Organisation for Economic Co-operation and Development (OECD) countries below are listed by the size of their motorway network and public road network.

Definitions

The OECD has defined a road to be:

Definition:

Line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels.

Context:

Included are bridges, tunnels, supporting structures, junctions, crossings and interchanges. Toll roads are also included. Excluded are dedicated cycle paths.

The OECD has defined a motorway as:

French Equivalent: Autoroute

Road, specially designed and built for motor traffic, which does not serve properties bordering on it, and which:

(a) is provided, except at special points or temporarily, with separate carriageways for the two directions of traffic, separated from each other, either by a dividing strip not intended for traffic, or exceptionally by other means;

(b) does not cross at level with any road, railway or tramway track, or footpath;

(c) is specially sign-posted as a motorway and is reserved for specific categories of road motor vehicles.

Entry and exit lanes of motorways are included irrespectively of the location of the sign-posts. Urban motorways are also included.

See List of highway systems with full control of access and no cross traffic.
