New York-based architect Candy Chan just launched Project Subway NYC to visualize some of Manhattan’s most complicated subway stations, blueprint style.

Chan says she was inspired by Hong Kong’s subway, which displays platform layout maps in each station. Exits are denoted by letter, and signs point you to individual exits rather than intersections, as they do in New York. In Hong Kong, Chan says, people often make travel plans by saying, for instance, “I’ll meet you at exit A.” (Now imagine telling someone to meet you at an entrance to New York’s Times Square station. Good luck with that.)
