TransitTracker
TriMet's real-time arrival information system
TriMet's TransitTracker™ provides real-time arrival information for buses, MAX Light Rail, WES Commuter Rail and Portland Streetcar. You can get the next arrivals for your stop online at trimet.org, over the phone at 503-238-RIDE, and on reader boards at MAX/WES stations.
Using GPS tracking and sensors in the MAX tracks, the TransitTracker system estimates when the next bus or train will arrive, based on the vehicles' locations and average speed.
TransitTracker gives you a better idea of when your ride is coming. Instead of standing at the stop, you may choose to wait inside, run another errand, grab a cup of coffee or finish one more project.

What to expect during a snow/ice storm
When many vehicles are off-route or significantly delayed, TransitTracker cannot make accurate arrival predictions. TransitTracker can, however, tell you if your line is canceled, or, in some cases, how far away the next vehicle is.
How it works
For buses and WES, TransitTracker uses Global Positioning System (GPS) technology to track how far the vehicle is from the stop. Every vehicle is equipped with a transmitter that allows satellite tracking with an accuracy of about 30 feet.
For MAX trains, sensors embedded in the MAX tracks record the speed of the train and the time it passes the sensor.
Portland Streetcar arrival information is provided by portlandstreetcar.org.
Arrival countdowns are estimates based on the location of the vehicle and the scheduled speed along its route. If the system can't make an accurate prediction (because, for example, the vehicle is too far away or if its transmitter isn't working), the scheduled time is displayed instead.
In the event of an emergency, TransitTracker provides important information and instructions to riders.
