Kilometre per square kilometre 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 (30.6 km/1 000 km2 in 1999, including Alaska and Hawaii and inland waters) but less than in Japan (53.5 km/ 1000km2 in 1999). For rail networkds, in Europe, the highest network density can be found in the Czech Republic, Belgium, Luxembourg and Germany (above 100 km/1 000 km²), followed by the Netherlands, Hungary, Austria, Slovakia, the United Kingdom and
