This rugged, simple-to-operate system increases flagger safety by allowing a single person to remotely operate two Automated Flagger Assistance Devices (AFADs) from a safe vantage point in or near the work zone.
An easy-to-use, weatherproof handheld wireless remote control operates the AFAD units and also displays the status of each AFAD. The remote control and each sign contain RF transceivers so that each command sent to the AFAD is continuously monitored and the unit’s display is verified on the remote control. A microprocessor in the remote control insures that it is not possible for both signs to simultaneously display amber signals without taking deliberate reprogramming steps.
Worker safety is enhanced since the operator can select a safe location that gives a clear view of all aspects of the work zone. The operator can observe the flow of vehicles at both ends of the zone, monitor crew members’ positions, and adjust the flow of traffic to allow for the entry and exit of construction equipment. 125 db. warning horns on each AFAD alert workers and motorists of potential danger and can be activated either by the operator or by a motorist striking the gate arm.
Gate arms reinforce the traffic control message. Breakaway gate arms are easily restored to operational position if bumped by a motorist. Arms stop descending without inflicting damage should they come down on a vehicle.
Retroreflective “STOP HERE ON RED” signs, gate arms and tall 12-inch-diameter red and amber LED signal faces communicate to the motorist that a flagging operation is in effect.
