The countries with the highest road quality

Infrastructure is an important factor for the productivity, safety and satisfaction in a country. Roads are used daily for a variety of reasons, and in order to build and maintain roads, costs are often high for the government. A poor road quality could also lead to potential accidents and carelessness. Road injuries are among the ten leading causes of death worldwide, taking 40,999 lives in 2019 in the U.S. alone.

Not only does the government have to appropriately divide the territory, it is also important that these roads have a high efficiency to allow commuters to reach their preferred destinations with as few struggles as possible. This is particularly important in larger countries, where cities are further spread out from each other. In terms of mileage, the United States has the longest and largest road network in the world, with approximately 6.6 million kilometers of paved or unpaved roads, while road density is highest in Western Europe and Asia.
