This dataset reports on the operation state of 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.

You can view an interactive map of flashing traffic signals here:

Approximately 90% of the City’s signals communicate with our Advanced Transportation Management System. When these signals go on flash, they will be reported in this dataset. Although we are extending communications to all signals, approximately 10% are not currently captured in this dataset. 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.

In this dataset the distinction between scheduled and unscheduled flash is identified by the 'operation state' column. A signal that is in unscheduled flash mode will have a status of 2 or 7. A signal that is in in scheduled flash mode will have a status of 1.

Austin Transportation & Public Works maintains road condition sensors across the city which monitor the temperature and surface condition of roadways. These sensors enable our Mobility Management Center to stay apprised of potential roadway freezing events and intervene when necessary.

This data is updated continuously every 5 minutes.

Code Officers are assigned cases based on 311 calls. These are then prioritized and updated by the Code Officers themselves. This dataset is uploaded to try and inform custom routing applications to better help Code Officers plan and route their days and be more efficient with their time.

This dataset contains traffic incident information from the Austin-Travis County traffic reports collected from the various Public Safety agencies through a data feed from the Combined Transportation, Emergency, and Communications Center (CTECC).
