Roboflagger Takes a Stand for Work Zone Safety on US 2Abstract:
A new kind of worker joins the ranks of WSDOT construction crews: the roboflagger. The roboflagger is WSDOT’s latest tool to make work zones safer for both driver and crews. Remotely controlled by a human flagger behind traffic safety barriers, the automated flagging device features red and yellow lights and a gate arm that lifts and lowers. The roboflagger keeps human flaggers safe by removing them from the direct line of traffic.
