Alpine Traffic Observatory: Annual Report covering the year 2013

While road transport within the EU is harmonized and thus based on common EU rules, road transport between the EU and non-EU countries (third countries) is still largely based on bilateral agreements between the individual Member States and the third countries. However, with certain countries the EU has concluded agreements which take precedence over the bilateral agreements.
