5 Countries With Most Efficient Public Transportation

4. Luxembourg

While many people have not heard of Luxembourg, it is a small European country bordering France and Germany. It may be important to note that the total land area of this country is relatively small at 2586 sq km, according to this report by the UNECE.

However, it would be amiss to not include Luxembourg’s high density of public passengers. This high number may be because public transportation in Luxembourg is free. For tourists: if you’re planning to visit, make sure you utilize their transport options and explore both the cities and the countryside.
