This incredibly thorough redesign is so convincing that it’s difficult to believe that it’s not officially authorized, but apparently it’s a self-initiated undertaking by Constantine Konovalov, the “former lead designer of integrated transport navigation at the Moscow Department of Transportation.” He and his collaborators have gone to enormous lengths to create a shockingly viable alternative to the city’s official map; the end products are not only highly professional and even concrete (you can download them in various forms for various uses), but the work shows a highly refined thoughtfulness. You can see this in their decision to use a “circular line pattern” as an organizing principle around which the lines and geography are subtly but meaningful redrawn to enhance clarity. You can see how this works in practice in this process video:
