All roads to Rome: Visualizing mobility at scale

The proverb ‘all roads lead to Rome’ is, by a closer look, a very interesting suggestive mobility statement. The goal of the ‘Roads to Rome’ was to find an automated way to visualize this saying. During the process of finding the right methods and approaches the authors encountered several inspiring further threads of ideas. The authors created maps using algorithms for routing from multiple starts to a single destination and also multiple destinations. The researchers also used the developed methodology on a small scale to visualize mobility network diagrams of selected cities. The resulting images are not only visually intriguing, but also allow conclusions about how road infrastructure reflects regional, political and geographical situations.
