Mapping the Transit System of Rio with GTFS data

Here is my first experience mapping a transit system using GTFS data!

The map shows the bus public transport system of the city of Rio de Janeiro as of November 2014. The blue lines represent the bus routes, where color intensity and width vary according to service frequency per day. I have also included the city's street grid in the background (gray) to give a visual idea of the transport system coverage.

The map was created in R (ggplot) using data from OpenStreetMap (OSM) and GTFS data provided by Fetranspor/Va de onibus (this is basically the same transit data people have access to in their mobile apps). This great map by James Cheshire was the main inspiration, although I couldn't get to such a nice result as James did.

I've created this map a couple of months ago but still need to organize the R code before sharing it here with you. I am also working on an interactive version of this map, but this may take a little longer  I've been facing some deadline issues lately  Stay tuned.
