"The CTA on Monday will launch a developer tools Web page on the transit agency's Web site, www.transitchicago.com. The page will allow developers to more easily download Bus Tracker and other transit data for creating desktop applications, widgets and mobile applications, and present it to their audiences to help improve travel planning.

The pilot project represents an opportunity to greatly expand access to Bus Tracker ( www.ctabustracker.com) information beyond computers, BlackBerry-like cell phones, personal digital assistants and other mobile devices."

One early use of the data is a screen at a group of Wicker Park businesses that display the estimated arrival times of CTA buses.
