ChiTransit is built on public open data. Our servers download each feed from the publisher's servers, store it, and serve it to you from our own servers. Information on this site may not be real time, may contain errors and is provided as is. For official information, use the operator's own channels.
| Feed | Publisher | How we use it |
|---|---|---|
| CTA scheduled service data ('L' trains and buses: stops, routes, trips and stop times) | Chicago Transit Authority (CTA) | Trip planner, schedules, station and line pages. The CTA updates this data generally once every week or two; we reload it when it changes. |
| Metra schedule data (all Metra lines and stations) | Metra | Trip planner, Metra and schedule pages. Metra updates this data regularly; we check for updates daily. |
| Feed | Publisher | How we use it |
|---|---|---|
| CTA Customer Alerts (service alerts and elevator status) | CTA | Fetched periodically by our server for service status and elevator outages. |
| CTA Train Tracker and Bus Tracker | CTA | Real-time arrivals where available. When no live prediction is available, we show the scheduled time. |
| Divvy station availability feed (station locations, bikes and docks available) | Lyft, operator of Divvy | Fetched periodically by our server for the Divvy page and the map. |
CTA data is used under the CTA Developer License Agreement & Terms of Use. Data provided by CTA. As those terms require, we do not state or imply any affiliation, sponsorship or endorsement by the CTA, and we do not use CTA marks in our site's name.
Metra data is used under Metra's developer license agreement. ChiTransit is not sponsored, affiliated with, or operated by Metra. We obtain the data from Metra and redistribute it through our own servers; we do not claim that it is accurate, complete or timely.
Divvy data is published by Lyft Bikes and Scooters, LLC; Divvy system data is owned by the City of Chicago. We do not state or imply that ChiTransit is affiliated with, approved, endorsed or sponsored by Divvy or Lyft.
Fare and service information in our guides (including fares and airports) is checked against the official websites listed on each page.
