Welcome to Port Authority of Allegheny County’s TrueTime℠ System

Real-time vehicle tracking is now available for most bus routes.

Remaining bus routes and additional features will be added at a later date.

Plan your trip with Google Maps:

Depart Arrive

A note about delays and detours:
If a bus is delayed in traffic, the arrival prediction may take longer than normal to count down or may adjust upward to reflect the delay.

TrueTime℠ is in the first stage of implementation and cannot currently display bus detours. Detoured buses will not be displayed on the tracker until they return to regular routing.

Buses will be removed from the tracker if they are taken out of service due to a break-down or other issue. In the event that a bus stops transmitting its location data, it will not appear on this website, even though it is in service. Additionally, buses without GPS-enabled head signs will not be tracked.

When viewing arrival times by stop, buses more than 30 minutes away from the stop will not be displayed.
