Exploring the art of subway tracks
I love creating things based on subway maps.
Losing myself in something designed to prevent others from getting lost is a wonderful irony. Most of us are familiar with maps focused on wayfinding and less on geographic accuracy. I wanted to explore the parts that make up geographically accurate maps and create something for others like me who love them.
Maps of major subways systems were broken down into the segments between each station and rearranged to fill a common simple shape: a circle. Each diagram shows every segment in a subway system while maintaining geographic orientation (no segments were rotated). Some segments serve multiple lines, like in in Chicago where the segment between the Washington/Wells and Quincy stops serves the Purple, Pink, Orange, and Brown lines. In these situations, a segment was included or each using that line's color. Some segments are longer because they represent skipping different schedules serving the same stations.
Arranging the segments this way reveals identities for city. Chicago is a grid-based city from north to south and east to west so its diagram has mostly horizontal and vertical segments while London's segments appear more curved because the city's layout is less rigid. New York City's layout has grid-based areas but they're on an angle from true north, so most of the lines are diagonal.
