Dave Peck's Software: Transit Score API

(Summer 2010)

I designed and implemented the new Walk Score Transit API, which returns the Transit Score for a given location and allows developers to easily query for nearby public transit routes and stops.

The API front-end runs on Google App Engine and handles millions of daily requests. The Amazon EC2 back-end watches for updated GTFS transit feed data from hundreds of public transit agencies. Once new data is found, it is pre-processed and uploaded to App Engine.

You can see Transit Score in action by visiting the Walk Score Home Page and typing in your address.
