According to the map, the length of the road network in the world is about 21 million km, of which 14% is in the United States alone.
This road network covers major highways and rural roads, according to the map published on the “Visual Capitalist” website.
To create the map, Symington used the Global Road Inventory project, which includes data from governments, research institutes, NGOs and crowdsourcing initiatives.
According to the British Daily Mail, the roads have been classified into one of 4 categories and have been color coded accordingly.
Major roads (multi-lane highways) appear white on the map, while minor roads (paved highways with heavy traffic) appear yellow.
Meanwhile, tertiary roads (residential roads on or off road) and local roads are marked in red on the map.
“This classification made it possible to examine the relationships between road infrastructure, development, wealth and population distribution,” explained the Visual Capitalist website.
The data reveals that of the 21 million km of roads in the world, 3 million km are in the United States, about twice China’s road network, which is 1.7 million km long, and 3 times that of India, which has about a million km roads.
At the other end of the scale, the small Pacific island of Palau has the smallest road network, at just 18 kilometers.
“However, many countries have smaller grids, and Norfolk Island is the smallest in the dataset at just 10km long,” Visual Capitalist added.
However, when breaking down road networks by type, China tops the list of major roads, followed by the United States and Mexico.
According to the map, there are large areas in Africa and Australia that have no color thanks to large areas with no roads, such as deserts.
