CTA Line Simplification

Full Screen

Created by Christopher Manning

Summary

Line simplification of the CTA train routes. Different line interpolations and simplification levels create interesting designs.

I created this because I like line simplification, d3.js, the CTA train map, and abstract geometric shapes.

extract_gtfs.rb extracts the train lines from a GTFS zip file and creates a GeoJSON file.
