Circular Paris

If you depict the metro lines and on a geographic map of the city, you will see a closed loop that does not represent a perfect circle. But, on the associative level, this loop is easier to remember in the form of a circle.

Usage of circular line pattern is the main principle of the map's design. They simplify the perception of the map by putting the visual accents and dividing the map into round segments.

In addition, these lines, forming a circle, are unique as they intersect with all the main lines of the system.

By the year 2030, another circular line will run around Paris.
