TRS: Mobile Traffic Signals in Lieu of Flaggers for Moving OperationsStatus: CompleteReport Date: 06/14/2013 Summary: Flagging in work zones is crucial to the safety of workers and drivers, but it is one of the most dangerous tasks, representing more than one-third of injuries to pedestrian workers. Automated Flagger Assistance Devices (AFADs) are portable traffic control systems that can help to improve safety because flaggers can operate them from outside the flow of traffic. Several states have evaluated AFADs, with generally positive assessments of their effectiveness. While compliance with the AFAD is not universal among drivers, violation rates were lower than red-light violation rates documented in other literature. MnDOT requested information about self-propelling AFADs for mobile work zones, with the specific idea of mounting an AFAD on a remote-controlled caravan mover.
