Certainly you could opt for a postcard of your favorite city’s key landmarks, but that doesn’t tell you all that much about the city’s culture does it? For a graphical element that speaks to the individuality of each city, all while depicting the landmarks that define it, mail those postcards and instead study a transit map. Some iconic, others unheralded, a transit map offers visitors a fingertip guide to the chaos of a city and arranges it in a way that holds true to the roots of the city.
Whether using a geographical framework (i.e. New York) or a schematic design (known as a diagram and used by most American cities), cities often swirl those ideas together, bending train lines and inserting key landmarks to help tell the story of both transit stations and cultural interest.
