Abstract:Automated Flagger Assistance Devices (AFADs) are remotely operated temporary traffic control equipment with high visibility signage, 12 inch red signal heads, and automated flags. These devices are intended to direct and control traffic using only one person. In a typical flagging operation, flaggers are located at each end of the lane closure and use Stop/Slow paddles to direct traffic while positioned in the travel lane. AFADs are used to remove flaggers from the traveled way in Temporary Traffic Control (TTC) zones. A flagger can operate an AFAD by using a radio control unit or a cable directly attached to the AFAD. In either case, the flagger can be positioned well away from the roadway and moving traffic. The primary benefit of this arrangement is to enhance the safety of flaggers while also maintaining positive control of traffic approaching the TTC zone.
