This dataset reports the progress of the Austin Transportation Department's Annual Signal Timing Program. Traffic signal engineers re-time approximately 1/3 of the city’s 1,000+ signals each year, with the goal of ensuring signals are timed for optimum safety and performance.

This data powers our Signal Re-timing dashboard, available here:
