How to Track Departures on Your Transit Line

Public transit can sometimes be a guessing game. Can you trust that departure time? Will the bus show up? That’s why we’re here: open the app and you’ll see when the departure is in real-time, when you have to rely on the schedule, or even if your trip was cancelled.

Here's what this article covers:

Check Real-time Information on the Home Screen

You can check if a departure time in the app is real-time by looking for two pulsating waves next to the countdown.

If these waves aren't present, the times in the app will be greyed out to show the posted schedule, and won't reflect any delays or service changes.

Tap any line on the home screen to see additional upcoming departures. You can then tap “more departures” to see the line’s complete schedule.

Identify Real-time, Scheduled, and Cancelled Trips

Real-time

When you see real-time waves next to a departure and a bus or train icon on the map, that indicates that you’re looking at real-time information!

Scheduled

When the departure time is greyed out, that means we’re showing you the scheduled departure time. We know scheduled arrivals aren’t always the most accurate, which is why we try to display real-time information whenever it’s available.

Cancelled

Sometimes trips are cancelled: maybe the vehicle broke down, or there isn’t a driver available. To let riders know about a cancellation, transit agencies can add this information to the app in real time. (Not all agencies do this yet, but it’s becoming more and more common!) You’ll know a trip has been cancelled by your agency when the departure has a real-time symbol but it’s turned grey and is crossed out.

Likely Cancelled

If your line has real-time information for later trips but not for a trip that’s supposed to come first, we’ll analyze the data and determine if we think this scheduled trip has been cancelled. The trip will be greyed out and crossed out to let you know we don’t think it’s coming.

Where Real-time Information Comes From

Whenever possible, Transit provides real-time arrival information about your trip so you can get more accurate predictions about when it will actually arrive.

Here's how real-time works:

  • Transit agencies use GPS trackers in their buses and trains to monitor the position of the vehicle.
  • Then, they use the vehicle location to calculate a more precise arrival time for your stop.
  • They send this new arrival time to us and we display it in the app!

Since real-time arrivals are based on the actual location of the vehicle, they'll change depending on whether it’s running early or late.

While we would love to provide perfect real-time information for all transit services, we don’t actually operate the transit system. But there are things that can help improve real-time information available in the app:

  • If your transit agency doesn’t have real-time information in the app, help out your fellow riders by tapping GO to crowdsource the real-time location of your vehicle.
  • We’re also working in dozens of cities to come up with our own real-time predictions that are better than what you’ll find in any other app. You’ll see a notice in the app if they’ve rolled out to your city!
