TriMet-Gtfs-Map is a project mainly written in Python, it's free.
Decode and mine data in GTFS format.
GTFS is a General Transit Feed Specification, an arbitrary format database created by Google along with Portland's transit authority TriMet.
The GTFS is downloadable as csv files in a zip.
This package contains scripts to put the database back into a database (sqlite) and analyze the movement of buses and trains in the system visually.
I built this mostly as bits and pieces of code to do particular tasks. Look through the code and use the useful ones with trimet data or transit data from any other source that uses GTFS to describe itself.
