In order to get a more comprehensive picture of Europe’s transnational transportation network, we decided to go beyond absolute numbers, taking into account the length of the borders and population sizes of each country.
Central European countries generally count between one and three transnational connections for every 100 km of border, with Austria, Czechia, Hungary, Slovakia and Germany holding the top spots in this particular ranking. Germany remains among the best-connected countries, despite boasting the longest border among the countries surveyed.

As for the number of connections per million inhabitants, the chart is obviously dominated by less populated countries such as Luxembourg, Austria, Slovenia, Slovakia, Switzerland, Czechia, Hungary and Croatia. However, the chart still confirms th
