Engage with developers, transit customers
Understand applications
and benefits

GTFS = General Transit Feed Specification
Created in 2005 by Google and TriMet
Now a de facto standard, it is is the most popularly-used data format to describe fixed-route transit services in the world
More than 200 transit agencies in the U.S. provide public GTFS data
Active, evolving standard
The full Spec is at

“The old limits of what unmanaged and unpaid groups can do are no longer in operation; the difficulties that kept self-assembled groups from working together are shrinking, meaning that the number and kinds of things groups can get done without financial motivation or managerial oversight are growing.”

Maintain ongoing relationships
with developers
We’re small and we can’t provide every customized solution people ask for…. making the data available is something that we’re very familiar with so that developers can develop the tools themselves. It’s like having an army of developers available to us.
— Tim McHugh,
CTO of Portland's TriMet
Open data facilitates innovation
Over the long-term, open data reduces IT burdens on agencies, allows focus on core business
Open GTFS data offers particular utility for multimodal "supernetworks"
air + intercity bus or rail
bike + transit
bikeshare + transit
rideshare + transit
carshare + transit
specialized demand-response + fixed-route transit
transit + carshare / taxi

Evolution and growth
gtfs-changes list
GTFS producers and consumers (transit agencies and app developers) discuss potential changes
demonstrable, useful changes are adopted
https://groups.google.com/group/gtfs-changes
some potential changes under discussion:
expansion of capabilities to describe fares: peak/off-peak, day of week, line-to-line transfers, etc.
station pathways
capability to describe hail-and-ride, flex-routes, and other demand-response services
