What are Automated Flagger Assistance Devices (AFADs) used for?

AFADs are used to keep traffic moving and protect workers by letting the flagger operate from outside the travel lane while motorists receive clear STOP/SLOW or direction signals from the device. This setup is designed for temporary traffic control zones, where a flagger would normally stand in or near the lane to guide vehicles, but the AFAD allows that signaling to happen from a safer location. The flagger still plays a critical role and must supervise and control the device, responding to changing conditions and intervening if drivers don’t follow signals. AFADs are not meant to replace flaggers entirely, and they’re used in short-term, temporary work zones—not in long-term setups or with no human oversight.
