Plotting GTFS Bus Routes and Stops on Google Maps

March 25th, 2009

I recently started playing with the public GTFS feeds (Google Transit). I’ve imported everything into MySQL and I’m working on some fairly cool applications for dealing with this data. Using some ExtJS components mixed with some Google Maps API pieces, you can create some pretty cool applications.

I’ve got a transit route viewer that reads JSON requests from the database. The underlying JSON server needs some work, so this is a static representation pulled from the database, but you can see the Denver South Broadway (0 Route) map with the link below.

This plots a polyline for the shape of the route defined in stop_times linked to stops and plots each stop along the route as a marker. Once I get a decent JSON implementation working, I should be able to provide a more dynamic route viewer.
