To get a general sense of pattern in Rochester, I began by using the Google aerial below to generate some urban graining through Grasshopper [GH].

By using a bitmap image, GH assigns values to points based on black and white values.  From those points, a Voronoi diagram [red] is created to get the following [thin green curve = approximate subway line]:

With further GH mappings, a series of estimated influence points began to populate the subway line, creating an interesting pattern of impact:
