What is a Ghost Bus?

You’re waiting to catch your bus. The schedule app says it’ll be there in two minutes. You wait, and no bus comes. Now you’re stranded. Should you spring for an expensive rideshare? Should you start walking?

If you’re a regular rider of the CTA, odds are you’ve been “ghosted” by your bus. While the pandemic put an understandable strain on transit systems, these days Chicago residents have commitments that require travel, and the CTA is struggling to keep up. Most importantly, the CTA's official schedules do not represent this change in service, leading to confusion, delays, and a general sense of distrust in our city’s public transit.

Ghost Bus is a Chi Hack Night project conducted by volunteer data scientists, engineers, and researchers. Our project compares open source real-time bus tracking data to the CTA’s official schedules to identify gaps in service across Chicago’s bus lines.
