With around 620,000 inhabitants, Luxembourg is one of the smallest countries in Europe. At the same time, however, it is also the country with the largest gross domestic product per capita. The accompanying prosperity, the broadly developed infrastructure and the common company car practice result in a very high number of vehicles in relation to Luxembourg's inhabitants. The consequence: traffic chaos and congestion. Not least due to the 200,000 commuters from neighbouring countries like Germany, Belgium and France who regularly cross the border. A solution was needed to counteract the trend: For the climate and free roads.
