Austin Traffic Signal Operational Status Reports

City of Austin data reports the operation state of traffic signals, distinguishing scheduled from unscheduled flash modes. Approximately 90% of the city's signals that communicate with the Advanced Transportation Management System are captured when they enter flash status.

Use Cases

• Classify signal events as scheduled or unscheduled flash using the 'operation state' column values (1, 2, or 7).
• Monitor network communication reliability by analyzing gaps in reporting for the approximately 10% of signals not captured.
• Identify patterns in unscheduled flash events (status 2 or 7) to prioritize maintenance for power or equipment issues.

Strengths

• Covers approximately 90% of Austin's traffic signals connected to the city's management system.
• Provides a clear classification for flash events via the 'operation state' column.
• Data is maintained by the authoritative City of Austin organization.

Limitations

• Does not include data for approximately 10% of city signals lacking network communication.
• Outages that disable both the signal and its network connection are not reported, creating a coverage gap.
• Data is for informational purposes and not intended for legal, engineering, or surveying use.
