“Roads to Rome” is a data visualization project that explores the idiom, “all roads lead to Rome”. The outcome is both information visualization and data art and unveils mobility patterns at a very large scale. The visualizations were created using routing algorithms on existing street infrastructure from city to continent scale. The resulting images bring insights into the ways in which road infrastructure reflect regional, political and geographical situations.
The project page comes with detailed informations, interactive maps, an “explore” app, media downloads … and can be found under:

The projet uses OpenStreetMap data and the open-source routing engine GraphHopper.
