Are Our Transit Maps Tricking Us?
Schematic maps, by necessity, balance between detail and readability. “If you try to get everything in, it becomes meaningless, usually,” says Lance Wyman, who designed D.C.’s Metro map more than 30 years ago and is redesigning it to incorporate the new Silver Line. When Wyman, who also designed the Mexico City Metro map (as well as the logo for the 1968 Mexico Olympic Games), sits down to convert a wily transit system into something people can understand, he aims not just to make it readable, but to enable each viewer to describe it to a friend. The stations need to be sequenced correctly, and their intersections must be clear.
