Roads of the Roman Empire

Scientists have discovered that Roman roads covered almost twice as much land as previously thought.

Analysis of every road used or built by the Romans during their conquest of Europe and beyond has revealed that they had an extensive network of 300,000 kilometers covering 2.4 million square kilometers.

This, scientists say, is "almost twice the length" of what this road network was previously thought to be.

An interactive map shows an interconnected empire that connected major cities that existed at the time and still thrive today.

The map exposes areas along the borders of the empire where the Romans fought to gain and hold territory. For example, much of Germany north of the Rhine is untouched by Roman infrastructure, reflecting the resistance of the Gothic tribes.

Ireland was never conquered by the Romans, and much of Scotland also remains free of roads after attempts to avoid invasion, despite occasional instructions.

"This increase is due to a higher road coverage (e.g., Iberian Peninsula, Greece, North Africa), but also to the decision to create a clear spatial datum that adapts roads to geographic reality (that is, to cross a mountain, our roads follow a winding path instead of a straight line), resulting in a higher number of vertices for road lines and a higher total length," the scientists write in their paper.

The study found almost 15,000 different road segments, but only 2.8 percent of the roads are safe, the scientists add.

Almost 90 percent of the routes are just guesses based on evidence other than their physical finding, and 7.5 percent are hypotheses.

One-third of the roads are considered major highways for era traffic, while two-thirds are small secondary roads, the scientists said.

The study is published in the journal Scientific Data and the Itinerary can be viewed here .
