These are the style and data files that make up the transit map built for Macon, Georgia during its 2012 Code for America partnership. The Macon Transit Athority now uses it on their website.
You can also view a large version here. You can view a medium-sized version with a fun CSS legend here. So many options.
We <3 Open Source
Everything we do is open source, so take it and use it! If you have a city that is exactly like Macon - same streets, same boundaries, same bus routes - you'll find this very useful! If not, it may still be useful to check out how it was styled.
If have more questions - let jllord know.
The slides from my talk at State of the Map US in 2012 are in this repo.
