What is this?
CTA Bus Tracker uses GPS devices to report bus location data (and more) back
to our servers. We can then, in real time, show you where buses are on a map
and estimate when they will arrive at your stop.
A note about delays and reroutes
Please note that if a bus goes off its regular route, our system
will no longer be able to predict accurate arrival times, will not be
able to automatically predict when it will return to normal service,
and may not be able to show the bus on our map. Please check for service alerts.
If a bus is unable to move for several minutes due to an unusual event
(such as stopped by a freight train at a crossing), arrival estimates
will switch from counting down minutes to a "DELAYED"
notification. Once the bus begins to move again, arrival estimates
will appear again. In the event that a bus stops transmitting data
to our servers, it will not appear on this Web site, even though
it is in service.
