Kilometre per square kilometre


Kilometre per square kilometre is an SI derived unit of reciprocal length used for measurement of density of a linear feature in an area. It is used to measure, for example, drainage density or road density.

Transport density in the European Union

In the European Union, Kilometer per square kilometer is the unit of measure of transport network density.

Motorway density

According to Europa.eu,
Usually, the densest motorway networks are found around capital cities and other big cities, in large industrial conurbations and around major seaports.
The regions with the higher motorway density are:
For cities, most cities are rounded by a motorway ring, so the density metric is dependent on the size of the city:
EU-15 had 48.3 km of railways per 1 000 square kilometres in 2000), more than in the United States but less than in Japan.
For rail networks, in Europe, the highest network density can be found in the Czech Republic, Belgium, Luxembourg and Germany, followed by the Netherlands, Hungary, Austria, Slovakia, the United Kingdom and Poland. At the lower end of the range are Turkey, Norway, Finland and Greece, with values of 20 km/1000 km² and below.
