An attempt to do something interesting and useful with GTFS data
This is a Rails project to attempt to do something useful with GTFS data.
The questions you should be able to answer are:
Routing is done with a messy A* algorithm. It's pretty slow - I suspect most of the problem is due to my data structures imposing higher big-O on my access to frequently needed data. Also, I'm guessing a poor choice of indexes for my data - playing with that now.
The GTFS Spec is at http://code.google.com/transit/spec/transit_feed_specification.html
It's based on Andy Atkinson's gtfs-helper project, but I rewrote it sufficiently that I decided not to fork, but just start over. He's at https://github.com/andyatkinson
