According to McKone, "Moscow's new map took four years to develop, according to the design firm behind it, Art. Lebedev Studio. Its design is meant to be scalable to various sizes and complexity. A lot attention was paid to graphically representing the intersections of various transit lines.
Graphic designer Cameron Booth, who redesigned Washington, D.C.'s Metro map as a personal project (it's not publicly in use), answered a few of our questions about mapping. First off, Booth says transit maps are not really maps at all; they are 'diagrams that show connections between points and not the accurate geography of an area.' New York City's subway map is the major exception to this rule.
