About Signals on Flash

What am I Looking at?

This dashboard reports flashing traffic signals in Austin, TX. Traffic signals enter flash mode when something is preventing the signal from operating normally. This is typically the result of a power surge, power outage, or damage to signal equipment. A signal may also be intentionally placed into flash mode for maintenance purposes or be scheduled to flash overnight.

Advanced Transportation Management

Approximately 90% of the City’s signals communicate with our Advanced Transportation Management System. When these signals go on flash, they will be reported on this dashboard. It also occasionally happens that the event that disables a traffic signal also disables network communication to the signal, in which case the signal outage will not be reported here.

Report an Issue

To report an issue or request a new traffic signal, call 3-1-1. You can also submit a traffic signal service request online.
