    • Traffic Signal Change and Clearance Interval Pooled Fund Study Arizona Video Data

    Metadata Updated: December 19, 2025

    The dataset consists of short video clips (approximately 20 seconds each) capturing traffic intersections in Arizona as part of the ITS JPO's Traffic Signal Change and Clearance Interval Pooled Fund Study. Each clip focuses on the yellow-light phase of traffic signals, providing visual data of vehicle and pedestrian responses during this transitional period.

    Similar datasets exist for Utah and Florida. Intersection summary and crash data, Basic Safety Messages, and Signal Phase and Timing message data are also available for this project.
