The warrant list procedure
Traffic signal, left turn arrow, and pedestrian corridor warrants are studies to determine if traffic control devices are needed at a specific intersection. A device is considered warranted if it passes this test. However, the traffic control device may not be approved for construction for different reasons, such as budget constraints or community association concerns.
Reporting an intersection issue
To submit a warrant request, or to report an issue with a signalized intersection (e.g., unusual delay or a perceived change in the basic signal operation), call 311.
