<pre>How many exact roads lead to Rome

The well-known proverb “All roads lead to Rome” has its own history. The Roman Emperor Augustus in 20 BC. e. by his decree established the so-called golden milestone – Millarium Aureum, a column with the names of capitals of provinces of the Roman Empire and distances to them. It was from her that all the roads of Ancient Rome began. However, this story has its continuation.

Designers Benedict Gross and Philippe Schmitt developed an interactive map that shows all roads originating in Rome using the Google Maps service. The result is an image of an extensive road network, something reminiscent of a branchy tree and consisting of almost 500 thousand routes.

It was not an easy job. At first, they recorded 486,613 starting points on an area of ​​26.5 million km2 – practically throughout Europe. Then they created an algorithm that calculated the alternative routes for each trip. The more often a segment of the road was used, the fatter it became on the map.

But Gross and Schmitt did not stop there. In the process of research, they found that a city with the name “Rome” is found in many countries of the world. Only in the US there are 9. They decided to create a map of routes connecting every American Rome with other cities of the continent. In just 2 hours, an algorithm was needed to create 312719 such routes.

(function (d, s, id) {   var js, fjs = d.getElementsByTagName (s) [0];   if (d.getElementById (id)) return;   js = d.createElement (s); js.id = id;   js.src = “//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8”;   fjs.parentNode.insertBefore (js, fjs); } (document, 'script', 'facebook-jssdk'));
