Open Data from CTA

CTA publishes a variety of data that we expect will be useful to software developers, researchers, urban planners, journalists and businesses, as well as interested citizens.

We encourage you to explore our data and make use of it.

If you have feedback about our data, send us an e-mail at webmaster@transitchicago.com and we'll do our best to respond to your inquiry.

General Info

How to view our data

You can browse any of the datasets listed on this page online by following the links below. Many datasets can also be exported for analysis or incorporation into software or other systems.

Hosted by the City of Chicago Data Portal

The City of Chicago has engaged in an extensive open data program through their data portal at data.cityofchicago.org, releasing hundreds of datasets about how the city does business.Through a partnership with the City of Chicago, data from CTA, as a peer agency, is being hosted in the city's data portal. The portal offers powerful, robust features for viewing, visualization and retrieval of public data.

Developers

If you're a developer, you can also embed these datasets in Web pages or interact with them directly through APIs (as part of the Socrata platform), which powers the city's data portal. Additionally, our Developer Center also contains live data feeds.
