Open Transit Data
Open Transit Data (OTD) is the bank of publically-accessible transit data for the Puget Sound region managed by Sound Transit
What it is
Free and accessible - we ask that you agree to our terms of service but beyond that you are free to use the data how and when you like. Request an API key or download the files.
A community - people that love transit, people that like to work with data, people that help build things. See our resources page for where and how to find your peeps.
What it isn't
Static - at a minimum, most agencies issue a service change twice a year. Some are constantly tweaking routes, stops and schedules. We strive to keep it current, but it is constantly evolving.
Comprehensive - we continue to add services and agencies, including expanding the real-time offerings. See the roadmap below for what's currently on tap.
Who it's for
Anyone that has an interest in transit data, from students interested in maps and urban planning to developers looking to produce the next great app that will blow everyone away. Maybe you just want to code a little more efficiency into your own commute!
Major updates from most agencies were processed and published on 9/12. Fall schedules are now in effect.
